OPERATING & MAINTENANCE INSTRUCTIONS
CHANGING BATTERIES
When the
icon on the transmitter or receiver, or the
icon on the receiver begins to flash,
it’s time to change the power source of the indicated unit.
Before proceeding to change the transmitter’s “9V” battery, power off the unit and all circuits to
which it is connected and remove all connecting wires.
Detailed instructions for changing the transmitter’s battery and the receiver’s batteries are found
on p. 7 of this manual.
If you do not expect to use the transmitter or receiver for a relatively long time (several months),
remove its battery to avoid the possibility of battery acid leaking and causing damage.
CHECKING AND REPLACING THE TRANSMITTER’S FUSE
The transmitter’s fuse is designed to prevent the unit from being damaged by overload or misuse.
If the fuse blows, the transmitter will be able to transmit only weak signals. If the unit passes its
functional self-test but the signal it generates is weak, it is likely that the fuse has been blown. If
the self-test detects no generated signal and the battery is adequately charged, it is likely that
the entire unit requires repair. In this case, if the CL10 is under warranty, contact General’s
Customer Service Department to arrange to return the unit for repair.
To check whether the transmitter’s fuse has blown:
• Disconnect the transmitter from all external circuits.
• Plug in both test leads.
• Power on the unit and press the
LEVEL SEL.
button to choose Level I.
• Press the
START/STOP
button.
• Power on the receiver and move its probe near the red test lead.
• If the fuse has not blown, the receiver will display a strong signal.
If the fuse blows while the CL10 is still under warranty, you should contact General’s Customer
Service Department to arrange to return the transmitter for outfitting with a new fuse. While the
unit is under warranty, you should NOT attempt to replace the fuse yourself. Replacing the fuse
requires opening the transmitter’s housing, and doing so voids the warranty because it could
disable the unit’s internal safety circuits.
If the fuse blows after the warranty period has expired, you can replace it yourself with a fuse of
the same rating and dimensions. The factory-installed fuse is a single-metal-wire, fast-acting
type. DO NOT replace it with either a helical-metal-wire fuse or a slow-blow unit.
