Low Battery warning
A series of vertical bars at the top right-hand side of the display screen indicates the
state of charge of the rechargeable batteries.
When there is a single bar of battery life left, it is time to recharge the batteries or
replace them with another battery pack. If the batteries become completely
exhausted the single bar of battery life will flash and then the instrument will
automatically switch off. Make sure the batteries receive a full recharge.
To recharge the batteries, simply plug in
the battery charger lead to the socket on
the top end of the instrument and plug
the charger into the mains. The batteries
will be fully charged in about three
hours.
Batteries
The GFM600 Series uses rechargeable Nickel
Metal Hydride cells.
To change the batteries, remove the two screws on
the rear of the instrument, then lift the battery
cover and remove the battery pack from the recess.
Place the new battery pack in the recess, making
sure that the metal contacts on the battery pack are
placed face down on the spring contacts in the
base of the battery box. Replace the battery cover
and secure with the two screws.
Always replace the battery pack in dry, clean
conditions, preferably indoors. NEVER allow
dust or moisture to enter the battery compartment.
