Maintenance
The only routine maintenance required for the Model VM-480B equipment and accessories is
to test and replace, if necessary, the batteries in the transmitter and the receiver. Both possess
battery test features, making it easy to check the condition of the batteries at any time.
We recommend checking the transmitter and receiver batteries before each use, preferably
before leaving for the job site.
7.1
Checking and Replacing the VM-480B Transmitter and
Receiver Batteries
Check and replace the transmitter and receiver batteries as follows:
1. Have ready 6 C Cell batteries.
2. To test the transmitter batteries, pull the power switch on. The LED will blink steadily if the
batteries are in good condition. It will begin to slow down as the batteries lose power. If it does
not blink at all, the batteries need to be replaced.
3.
To test the receiver batteries, turn the Range Knob to "NORM". The needle on the field
strength indicator should move into the BATT test area. If it does not, the batteries need to be
replaced.
4. To replace batteries in either the transmitter or the receiver, open the BATTERY ACCESS door
on the front of the unit. Extract the battery holder and replace batteries, positioning according
to the indications shown inside the battery holder.
5. Close the battery access panel, ensuring that there are no wires caught between the receiver
body and the access panel. Make sure the latch is securely fastened.
