To change the fuse
(if it blows following expiration of the 1-year limited warranty term), you
must open the CL10’s housing. To do so:
1. Turn the unit over and remove the two Philips-head screws at the top corners of the back
half of the housing.
2. Remove the one Philips-head screw securing the battery compartment cover to the back.
3. Lift the cover to expose the other two Philips-head screws securing the two halves of the
housing to each other. Remove those two screws as well.
4. Carefully separate the two halves of the housing as far as the two flanged connectors in the
battery compartment allow. The transmitter’s fuse—a white cylinder with silvered sleeves
on both ends—should be visible seated in its holder.
5. Carefully pry the fuse out of the holder and replace it with a fast-acting ceramic fuse with a
rating of 500mA @ 1000V and dimensions of 6.3mm (diameter) x 32mm (long).
6. Carefully reassemble the housing by replacing the five screws in the reverse order in which
they were removed.
OPERATING & MAINTENANCE TIPS
DO NOT expose either the transmitter or the receiver to:
• Direct sunlight
• High humidity or temperatures (above 104°F/40°C during operation or 140°F/60°C
in storage)
• Corrosive or explosive gas
• Excessive dust
• Strong mechanical vibration or stress (dropping, for example) or electromagnetic radiation
Before using a transmitter or receiver that has been subjected to extreme temperatures, allow
several hours for it to acclimate to your local conditions.
Do not open the housing of either the transmitter or receiver (except to replace the transmitter’s
fuse after the 1-year limited warranty period has expired). Opening the housing of, or
disassembling either unit voids the product warranty and could disable its safety circuitry.
You may clean the housing of the transmitter or receiver with a clean rag and water or a mild
detergent. Never use benzene, alcohol, acetone, ether, ketone, paint thinner or gasoline. After
cleaning a unit, allow it to dry thoroughly before using it again.
Use a rag dipped with clean water or neutral detergent to wipe the transmitter, and then use a
dry rag to wipe it again.
