- Secure Button: Attach the call button securely to the surface using screws.
- Label: Use a permanent marker to write the corresponding elevator number and floor number in the designated 'No.' and 'Floor' areas on the button's face.
2.2 Receiver (SC-R10GX) Setup
The SC-R10GX receiver should be placed in a central location where the elevator operator can easily see and hear incoming calls.

- Placement: Position the receiver on a flat surface or mount it on a wall within clear view and hearing range of the operator.
- Power Connection: Connect the provided power adapter to the receiver and plug it into a standard electrical outlet. The receiver also has an internal storage battery for backup power, providing 5-6 hours of standby time.
- Antenna: Extend the antenna for optimal signal reception.
2.3 Pairing/Registration
The call buttons must be registered with the receiver to function correctly. The system prevents re-registration of an already registered number to avoid conflicts.
- Enter Pairing Mode: Refer to the receiver's specific instructions (usually a button combination or menu option) to enter pairing mode.
- Press Call Button: While the receiver is in pairing mode, press the 'Call' button on the APE500.
- Confirmation: The receiver will typically display a confirmation message or sound to indicate successful pairing.
- Assign Number: Follow the receiver's instructions to assign a unique number to the paired call button. This number will be displayed on the receiver when the button is pressed.
- Repeat: Repeat this process for all additional APE500 call buttons. The SC-R10GX can work with up to 199 pagers.

4. Care and Maintenance
Proper care ensures the longevity and reliable performance of your SINGCALL system.
- Cleaning: Wipe the call button and receiver with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Battery Care (Receiver): The SC-R10GX receiver has a built-in storage battery. For optimal battery life, avoid fully discharging the battery frequently. Charge it regularly, especially during extended periods of non-use.
- Environmental Protection: While the APE500 call button is waterproof and durable, avoid exposing it to extreme temperatures or direct impact if possible.
- Signal Interference: Ensure the receiver is not placed near large metal objects or other devices that may cause wireless interference.
