Pairing with SYNLETT Pager (M091B / SP30)
To ensure proper functionality, the call button must be paired with a compatible SYNLETT pager. Follow these steps to program your call button(s) to the pager:
Step 1: Test and Check the New Call Button
- Turn the pager OFF.
- Switch the pager to the DINGDONG mode.
- Within 5 seconds, press and hold the new call button.
- Observe if the pager responds with a red light. If it responds, the call button is programmable.
Step 2: Program All Call Buttons to the Pager
This step programs all call buttons (existing and new) to the pager. If you have multiple call buttons, you will program them sequentially.
- Turn the pager OFF. Wait for 3 seconds.
- Quickly switch the pager to the DINGDONG mode.
- Immediately press and hold the first call button until the pager responds.
- Repeat the process for the second call button (if applicable): press and hold until the pager responds.
- Repeat for the third call button (if applicable): press and hold until the pager responds.
- After programming all buttons, the pager's blue light will flash, indicating successful programming.
Step 3: Final Check
It is crucial to test all programmed call buttons to ensure they are working correctly with the pager.
- Press each call button individually.
- Verify that the pager responds with an alert (e.g., green light for the first two, red light for the third, as shown in the video).
