3.0 Operation Instructions:

Battery Indicator:

The LED on the front of the transmitter indicates the condition of the batteries. It will

flash green during operation if the battery power is sufficient, and will flash red if the battery

power is low. If the LED is flashing red, or if the operation becomes erratic, or will only

work from a short distance, replace all 4 batteries with new AA alkaline batteries using the

procedure given in section 2.4.

2. Fuses

There are seven fuses in the F24-J-RX. There is one fuse in the AC power line that

operates the receiver (0.5A, 250V), and one in the internal 12 volt DC supply (1.5A, 250V).

There are five fuses in the COM wires (10A, 250V). The fuses on the COM wires are for

relay contact protection in the event of a short circuit in the equipment being controlled by

the radio. To replace a fuse, push down the fuse cover and turn counter-clockwise ¼ turn

with thumb and forefinger or a flat-blade screwdriver. Remove the fuse from the cover and

insert a new one of the same rating. Insert the fuse and cover into the fuse holder, press

down, and turn clockwise ¼ turn. For protection from fire hazard, damage, or injury,

always replace a blown fuse with one of the same rating.
