OPERATING MANUAL
PART 1 – OPERATION
AVW 150203 – 2010O&MPt1-Sec2.DOC
This indicates a timer that counts backwards, the time displayed being the maximum
time allowed to charge the batteries. If the batteries are charged before that time has
expired (counted down to zero) charging will be terminated and the unit switched off
automatically.
If it is necessary to terminate the charging cycle before the batteries are fully charged
and the unit has turned itself off, the charging cycle may be ended by pressing the X
key.
Step 3 The charging process is a rapid cycle program and is automatic. It will
terminate when the batteries are fully charged. Once it is activated the automatic timer
provides adequate time for exhausted batteries to be fully charged. Hence it should
not be necessary to re-run the charging program once it has completed the process
automatically.
NOTE: attaching the charger whilst the unit is turned off at the I/O switch (but the Main Power
Switch must be ON) will automatically trickle-charge the batteries. IMPORTANT: if the unit is
switched on at the I/O button whilst the charger is attached, the unit will go into charge
mode automatically (1
st
charging procedure).
• 3rd charging procedure (for completely exhausted NiCad batteries DU will not switch
on)
Step 4 Make sure the Main Power Switch in the battery compartment is ON
position. Connect the charger power cord to the mains supply outlet socket. Make sure
the socket is ‘live’. Leave the charger attached for a 30 minutes – applies to units
D/1669 or later. The charger will now charge the batteries. When the batteries have
been charged sufficiently the unit will automatically turn on and continue the charge
cycle. If unit fails to switch on, disconnect the charger, switch off (at switch) for 5
seconds, then on again – then proceed to 2nd charging procedure, step 1 above.
WARNING! In all above procedures the main switch must be ON before the
charger is attached..
NOTE: Attaching charger without batteries will start the detector in charge mode. Since
there are no batteries, they will not be charged. System will switch off in 4 hours or can
be aborted by pressing the X key.
If this has been done, disconnect the charger, switch the switch to OFF, insert batteries,
switch to ON. Then proceed to 2nd charging procedure, step 1 above.
