Re-learning is only required if the WTRVS is removed, but not required after battery
replacement. To remove WTRVS, you have to remove it from the Control Panel first
and then reset it to factory default.
III. Battery
The Wrist Transmitter uses one CR2 3V lithium battery as its power source. Please note:
ALWAYS replace battery with the correct size and voltage.
Press the Low Battery Detection Button to test the battery voltage. If the battery voltage is
low, WTRVS will respond for 3 short beeps. If the battery voltage is normal, WTRVS will
not emit beeps.
