belt has reached its maximum discharge state. See Section 2.5 for the table of
ODP trip voltages.
Additional to the above, the output sockets will also become isolated if the
cell temperature exceeds 70°C.
A single button is provided to reset these circuits and it is marked ODP reset.
If a battery belt is to be charged via an external charger the ODP circuit
should be reset if it has been tripped.
If the ODP circuit has tripped due to overheating of the cells, the belt must be
allowed ample time to cool (at least 1 hour) and the cause of the heating
established before the ODP circuit is reset.
Pagbelt IC2 incorporates an internal overnight charger. This charger is
independent of the ODP circuit.

GENERAL CHARGING INSTRUCTIONS.
Pagbelts must be charged only from constant current chargers. Constant
voltage chargers (as used for example for charging lead acid batteries) are
not suitable for use with Nickel-Cadmium batteries, and may damage them
irreparably.
When a battery belt has been discharged at high current rates it will become
warm, and it is advisable to let it cool before recharging it.
The recommended charging temperature range is 0°C to +40°C.
IC2 Pagbelts incorporate an internal overnight charger - see Section 3.3
below for operating instructions.
All Pagbelts may be fast-charged using the appropriate PAG microcomputer-
controlled fast charger. See Section 3.4 below for instructions.
CHARGING FROM INTEGRAL CHARGERS.
WARNING:
If moisture has entered the charger housing (such as may occur if
the belt has been immersed in water), it should be allowed to dry thoroughly
before being connected to the mains supply.
Ensure that no equipment is connected to the output connectors during the
charging process.
The charger housing will become warm in use. To allow adequate cooling,
do not place objects on or around the Pagbelt while it is being charged.
Connect the integral charger to the supply using the mains lead provided.
The charging indicator will light.
