86-8-64 DESCRIPTION AND OPERATION

With the batteries fully recharged, the handset can remain on stand-by for approximately 48 hours and has an air time 
of at approximately three hours. If the batteries are completely flat or if new batteries have been inserted, full charging 
will take approximately six hours. To charge the batteries, place the handset in the eject box. The batteries are also 
charged while the car is parked (ignition off).

The handset is connected with the base station in the car by radio link. This link can be switched off for workshop 
purposes or where it is a market requirement. When using the handset, ensure that this switch always remains in 
position "1" (to the right).
