How can I customize the beeper volume and delay on my Garage Door Minder M820-TXR?

[HarrisonLee]

To personalize the beeper settings on your Garage Door Minder M820-TXR Wireless Transmitter and Light Stick, follow these steps. To turn the beeper off completely, press the program button until a single LED lights up, and then release it. The beeper is now deactivated. To set the beeper to its maximum volume (100%), press the program button until two LEDs illuminate, then release. For a 50% volume level, press the program button until three LEDs light up and release. If you wish to revert to 100% volume, repeat the steps for turning the beeper on. For a 45-second delay before the beeper sounds, press the program button until the two center LEDs light up, then release. This sets the delay. Note that if you want to reset and delete all paired devices, this action will erase all auto-paired devices and return the unit to auto-pairing mode. If no transmitter is within range during this process, no pairing will occur. If the 30-second pairing sequence has ended, you can unplug the unit and plug it back in; it will beep and blink twice, indicating it's in auto-pair mode for 30 seconds.
