pressed, and the buzzer is enabled, it will be disabled, and the LED indicator will turn off. On the

The unit provides a BUZZER-KILL (turns off the BUZZER) system, so that when the buzzer is
enabled it is possible to muted it by the BUZZER-KILL function of the base station ALTAIR WBS-202 or
a master station ALTAIR EF-200, connected to the base station. This BUZZER-KILL system is
compatible with other intercom systems of the market.
The BUZZER could be disabled with an internal preset. In order to obtain more information,
consult the special operation section.

3.11 USB DC-IN CONNECTOR
The Li-Ion 1800 mA/h battery of the wireless beltpack must be charged with the ALTAIR
WBPC-210 charger by the USB connector.
Charging time is four hours with the batteries empty.
The estimated battery life, in full duplex mode is 15 hours and 100 hours in standby mode,
with full charged batteries.
The Li-Ion batteries have a protection system that disconnects the load when a short circuit or
when the battery down a voltage level, to re-enable the battery it is necessary plug it to the
charger.
The battery is discharging even with the beltpack off, so
for extended periods without using the wireless beltpack, the
battery may enter into a self-protection state, and start
charging very slowly (the LED charger does not turn yellow),
showing a critical battery message, do not worry, leave the unit
charging until it starts to charge normally (approximately 10
minutes). As a general rule, charge the unit before using the system.
