– If it is malfunctioning (no tone sounds).

• When replacing the fuse, be sure to use the supplied one. Using any other fuse than supplied may cause fire or electric shock.

To prevent moderate or minor personal injury, and/or property damage, please follow these cautions when installing and using your TOA VM-2240 system.

When Installing the Unit:

• [All models] Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

• [TOA VM-2240] Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.

• [TOA VM-2240] When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.

• [TOA VM-2240] When moving the unit, be sure to remove its power supply cord from the wall outlet. Moving the unit with the power cord connected to the outlet may cause damage to the power cord, resulting in fire or electric shock. When removing the power cord, be sure to hold its plug to pull.

• Do not block the ventilation slots in the unit’s cover. Doing so may cause heat to build up inside the unit and result in fire.

• To avoid electric shocks, be sure to unplug the unit’s power supply cord when connecting speakers.

When the Unit is in Use:

• [All models] Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.

• [TOA VM-2240] Make sure that the volume control is set to minimum position before power is switched on. Loud noise produced at high volume when power is switched on can impair hearing.

• Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a malfunction, which in turn can cause heat to generate and result in a fire.

• Contact your TOA dealer as to the cleaning. If dust is allowed to accumulate in the unit over a long period of time, a fire or damage to the unit may result.

• If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean it periodically. In addition, insert the plug in the wall outlet securely.

• Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric shock.

Follow these handling precautions for your TOA VM-2240, RM-200M, and RM-210:

• Cleaning: First, switch off the power supply to the unit, then wipe it with a dry cloth. For heavy dirt, use a cloth dampened in a neutral cleanser. Never use benzene, thinner, or chemically-treated cleaning cloths, as these volatile liquids could deform or discolor the unit.

• Moving the Unit (with EV-200M): If the EV-200M Voice Announcement Board is mounted, never move the TOA VM-2240 from one place to another with the CompactFlash card inserted, as this may cause the EV-200M or the card to fail.

• CompactFlash Card: Avoid inserting or withdrawing the CompactFlash card while the unit is powered on.

When installing your TOA VM-2240 system, please observe the following precautions:

• Do not install the unit in locations exposed to direct sunlight or heaters, as this could cause deformation or discoloration.

• Avoid dusty or humid locations to prevent unit failure.

• Keep the unit away from sources of high-frequency noise, such as fluorescent lamps, digital equipment, and PCs.

• For the TOA VM-2240 amplifier, do not block the ventilation slots on the upper, right, left, and rear sides. Maintain at least 50 mm of space on the right and left sides for heat radiation.

• Never connect the AC power cord to a line voltage other than the one specifically designated.

• To prevent oscillation, keep input cables away from output cables, especially when mounting in an equipment rack.

• If a ground loop causes hum noise, connecting the rear-mounted signal earth terminal to the body of connected equipment (like a BGM source or expansion amplifier) may reduce it.

• Never connect two amplifier outputs in parallel under any circumstances.

Caution: Any work that requires opening the amplifier’s top cover, such as mounting optional boards or setting switches, must be performed by a qualified service technician. Always switch the power off before such work.

The following is a typical example of an Emergency Broadcast operation using the RM-200 Remote Microphone with your TOA VM-2240.

Step 1. Alert Broadcast

Open the RM-200 Remote Microphone’s Emergency broadcast switch cover, and press the switch. A pre-recorded Alert signal and announcement will be broadcast alternately to the entire zone. The EMERGENCY indicators on both the remote microphone and the TOA VM-2240 will light up. This broadcast can also be activated by an external fire alarm system.

Step 2. Evacuation Broadcast

After the Alert broadcast repeats for a pre-programmed duration, the system automatically switches to the Evacuation broadcast, playing a pre-recorded Evacuation signal and announcement to the entire zone. This can also be triggered directly by an external system.

Step 3. Live Microphone Announcement

During either the Alert or Evacuation broadcast, you can make a live announcement.

3-1. Hold down the Remote Microphone Talk key. This will interrupt the current emergency broadcast and allow you to speak into the microphone to the entire zone.

3-2. When you release the Talk key, the microphone announcement terminates, and the system reverts to the Evacuation broadcast.

Note: In Emergency Broadcast mode, the Talk key always functions as “press-to-talk,” even if set to “lock” mode.

Step 4. Emergency Broadcast Termination

To terminate the Emergency broadcast, activate the Emergency Stop input from the connected external equipment. The unit will return to the general-purpose broadcast mode it was in before the emergency, and the EMERGENCY indicators will turn off.

Important Notes:

• Emergency broadcasts are always at maximum volume; master and zone volume controls are bypassed.

• The emergency broadcast cannot be terminated from the Remote Microphone.

• Pre-recorded messages and signals require the installation of the optional EV-200M Voice Announcement Board and a configured CompactFlash (CF) card.

Microphone Announcements (When Operated by Control Input)

1. Continuously press the microphone’s press-to-talk key. If it’s a lock lever type, set it to the ON position.

2. Make your announcement into the microphone.

3. Release the press-to-talk key (or set the lock lever to OFF) to end the announcement.

Background Music (BGM) Broadcast

1. Select the desired broadcast zone using the ZONE 1–5 keys or the ALL key on the TOA VM-2240 front panel.

2. Start your background music equipment (e.g., CD player).

3. Adjust the sound volume using the BGM input volume control on the front panel.

4. Adjust the tone using the BGM treble/bass controls on the front panel.

You can make four types of broadcasts from the RM-200M remote microphone: All-Zone, Individual Zone, Group, and Message. All announcements from the remote microphone are broadcast at maximum volume, bypassing the master volume, zone volume, and external speaker attenuators.

Common Steps (after selecting zones):

• Step 2. Check the Busy indicator. If it’s off, you can broadcast. If it flashes orange, you cannot broadcast. If it flashes green, you can interrupt the current broadcast.

• Step 3. Start of broadcast. Press (or press and hold for “press-to-talk” mode) the TALK key. A start chime will sound (if enabled), and the In-use indicator will light green. Make your announcement after the chime.

• Step 4. End of broadcast. Release (or press again for “lock” mode) the TALK key. An end chime may sound, and the broadcast will terminate. The In-use indicator will go out.

(1) Simultaneous All-Zone Broadcast

• Step 1. Press the ALL-ZONE key. The All-zone indicator and all zone indicators will light. Then proceed to the common steps above.

(2) Individual Zone Broadcast

• Step 1. Press the ZONE key for the desired zone. The corresponding indicator will light. You can select multiple zones. Then proceed to the common steps.

(3) Group Broadcast

• Step 1. Press the GROUP key for the pre-programmed group. The group indicator and the indicators for all zones in that group will light. You can select both groups simultaneously. Then proceed to the common steps.

(4) Message Broadcast (Requires optional EV-200M board)

• Step 1. Start of broadcast. Select the desired message with the MESSAGE key (1–5). The Message indicator will light, and the recorded voice message will broadcast to its designated group.

• Step 2. End of broadcast. The message indicator goes out when the broadcast is finished. You can also press the MESSAGE key again to terminate it early.

The TOA VM-2240 system uses a priority system where higher priority broadcasts interrupt lower priority ones. Upon completion, the original broadcast is restored. The priority levels are as follows, with underlined values being the factory presets.

The TOA VM-2240 offers three modes to handle simultaneous broadcasts from sources with the same priority level, which can be set via internal switches:

1. Last-come-first-served priority (factory-preset mode): The most recent broadcast takes precedence, interrupting any earlier broadcast to the same zone(s).

2. First-come-first-served priority: The current broadcast is given priority, and any subsequent broadcasts to the same zone(s) cannot be made until the first one is finished.

3. Unit number priority (numerical order): This applies to Remote Microphones (No. 1–4) and EV-200M messages (No. 1–5). The unit with the lower assigned number takes priority over units with higher numbers.

To mount your TOA VM-2240 amplifier in an equipment rack, follow these steps:

Step 1. Remove the 4 plastic feet from the unit’s bottom side.

Step 2. Remove the 2 screws on each side of the unit, located near the front.

Step 3. Using the accessory screws and plain washers supplied with the Rack Mounting Bracket MB-36, fix the bracket to the unit. Do not use the screws you removed in Step 2.

Step 4. Mount the unit onto the equipment rack using the bracket’s accessory screws and fiber washers. If your rack is not made by TOA, you may need to prepare appropriate screws and washers separately.

Here is an example of assigning Broadcast Zones 2, 3, and 4 to Group 2 on a single TOA VM-2240 (5-zone configuration).

Step 1. Enter broadcast group setting mode.

Press and hold the ZONE 1 and ZONE 2 keys simultaneously. While holding them, press and release the recessed Reset key with a pointed object. When all indicators for Zones 1–5 begin to flash (after 2-3 seconds), release the ZONE 1 and ZONE 2 keys. The unit is now in setting mode.

Step 2. Select the group number.

Press the ZONE 2 key to select Group 2. The ZONE 2 indicator will begin to flash slowly to confirm the selection.

Step 3. Enter zone selection mode.

Press the POWER switch. The unit will now be in Zone Selection mode for Group 2. The ZONE 2 indicator will change from “quick flashing” to “slow flashing,” indicating Group 2 is selected and Zone 2 is currently set by default.

Step 4. Set the zone numbers.

Press the ZONE 3 and ZONE 4 keys. The indicators for ZONE 3 and ZONE 4 will light up, indicating they have been selected and added to Group 2. Zones 2, 3, and 4 are now selected for Group 2.

Step 5. Program the zone number setting.

Press the POWER switch. The new zone assignment for Group 2 will be programmed. The unit automatically returns to Step 2, ready for you to select and program the next group.

Step 6. Complete the setting mode.

After all groups are programmed, press the Reset key with a pointed object. This will complete the setting mode and return the unit to broadcast standby mode.
