Using the Reset Button

Use the Reset button, on the back of the Telephony Modem, to reset the modem and
perform initialization as if you power cycled the unit. You may need to reset the Telephony
Modem if you are having problems connecting to the Internet. Using this button will be rare.
Use a pointed non-metallic object to press this button. The Reset button is recessed to
prevent accidental resets.

Booting from Battery

The TM822R supports a "Boot from Battery" feature that allows the Telephony Modem to
provide continued telephone service during power outages.
To start the TM822R from its battery, follow these steps:
1. If a battery is already installed in the Telephony Modem, remove it.
2. Re-insert the battery into the Telephony Modem. See
(page 15) for details.
3. Press the Reset button; the Power light should turn on immediately.
Note: If the Telephony Modem does not turn on, the battery may not be charged.
