SAMSUNG SM-A145R-DSN (01) PDF Document

The SAMSUNG SM-A145R-DSN has a Speaker, SIM card / microSD card tray, Front camera, Touch screen, Headphone jack, Rear camera, and Flash on the front/sides. On the back, it has a Side button (Fingerprint recognition sensor), Volume button, GPS antenna (SM-A145P, SM-A145R, SM-A146P), Main antenna, Speaker, and Microphone. The side button is for pressing and holding to turn the device on or off, pressing to turn on or lock the screen, and pressing twice to open a set app or feature. Pressing the Side button and Volume Down button simultaneously captures a screenshot. Pressing and holding them simultaneously turns off the device.

Charge the battery before first use or after extended periods of disuse. For wired charging, connect the USB cable to the USB power adapter and plug the cable into the device’s multipurpose jack to charge the battery. Disconnect the charger after fully charging. For quick charging, use a super fast charger or fast charger. You can check the connection status in Settings and tapping Battery. If fast charging does not work, check the settings under Battery → Charging settings to ensure the feature is on and the USB cable and power adapter are connected properly. Charging is quicker when the device or its screen is turned off.

To conserve battery power on the SAMSUNG SM-A145R-DSN:

Optimise the device using the device care feature.

When not using the device, turn off the screen by pressing the Side button.

Turn on power saving mode.

Close unnecessary apps.

Turn off the Bluetooth feature when not in use.

Turn off auto-syncing of apps that need to be synced.

Decrease the backlight time.

Decrease the screen brightness.

Use only Samsung-approved battery, charger, and cable specifically designed for the SAMSUNG SM-A145R-DSN. Incompatible items can cause serious injuries or damage. Connecting the charger improperly may cause serious damage not covered by the warranty. Use only the USB Type-C cable supplied with the device; using a Micro USB cable may cause damage. Do not charge the device if the multipurpose jack is wet; dry it thoroughly first. Unplug the charger when not in use to save energy. When using a charger, use an approved one for guaranteed performance. If the battery is completely discharged, allow it to charge for a few minutes before turning on the device. Battery drains quickly when using multiple apps, network apps, or apps needing external connections; use these after full charging. Using a power source other than the charger, like a computer, results in slower charging. The device can be used while charging, but it takes longer. If the device receives an unstable power supply while charging, the touch screen may not function; unplug the charger. The device and charger may heat up during charging, which is normal. If the battery gets hotter than usual, charging may stop. If charging is improper, seek service.

For the SAMSUNG SM-A145R-DSN (which includes SM-A145P, SM-A145R, SM-A146P models for SIM tray insertion):

Step 3: Place the SIM or USIM card on the tray with the gold-coloured contacts facing downwards and gently press the SIM or USIM card into the tray to secure it.

Step 4: Insert the tray back into the tray slot.

Precautions include using only a nano-SIM card, being cautious not to lose the card, ensuring the ejection pin is perpendicular to the hole to avoid device damage, making sure the card is fixed firmly, ensuring the tray is dry before insertion, and fully inserting the tray to prevent liquid entry.
