Rechargeable battery pack
11.7
The rechargeable battery pack cannot be changed at station. If
a ‘reduced battery’ icon is displayed investigate why i.e. is the
charging lead connected or is the charging point defective on
the appliance, try changing the set position to see if the
charging icon is displayed on the Bodyguard display:
•
Main power – 6.5 volts.
•
The Bodyguard is powered by a 6.5 volt rechargeable battery pack.
•
Actual operating time of the battery pack is dependent on how long the system has been
operating, frequency of alarms, ambient temperature and frequency of use of the backlight.
•
With the system switched ‘off’ a small amount of power is still consumed.
•
Note: All electronic devices may suffer a temporary loss of function if subjected to high levels
of radio frequency (RF) radiation.
•
The Bodyguard will continue to operate with no loss of performance or loss of function, once
the RF radiation has been removed.
