2.2 Battery Warning

CAUTION

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type

recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s

instructions.

The MR4800E Controller circuit board includes a battery that maintains the MR4800E’s setup

information when the MultiModemManager is turned off or disconnected from power. The battery can

maintain the setup information for approximately 10 years with no external power, and longer when

the MR4800E is turned on and operating normally. This battery is soldered onto the circuit board and

cannot be replaced by the user.

If, for some reason, the MR4800E’s battery should fail, please contact Multi-Tech Technical Support

at (800) 972-2439 for replacement instructions.
