BATTERY TESTING
11.1
Battery Check
The presence of a battery can be verified without opening the NRT/NRM.
Look for the flashing LED through the window on the front of the NRT/NRM unit.
If the NRT/NRM is in an idle state the LED will flash faintly once every second.
If the LED is not flashing, you will need to open the NRT/NRM and verify the presence of
a battery:
If a battery is installed, the NRT/NRM may be in sleep mode.
To wake the NRT/NRM, remove the battery, leave it out for 3 minutes, then re insert the
battery.
