7.0 Maintenance

WARNING

This equipment contains semiconductor devices and integrated circuits. Static electrical charge buildup in

the human body can destroy integrated circuits. Wear a commercially approved ground strap when

handling printed circuit boards containing integrated circuits. Wearing a ground strap discharges any

static charge buildup to ground and ensures the safety of the integrated circuit. For information on using

the ground strap, refer to the ground strap instruction manual.

Failure to follow these warnings may result in serious injury or equipment damage.

This section describes maintenance procedures for the L-854 Radio Control Equipment.
Prior to undertaking any maintenance to this unit, refer to Theory of Operation in the Description section.

7.1 Introduction

The only maintenance recommended by people other than skilled radio technicians is changing the fuses and circuit boards.

If a problem develops in the unit, make the following checks:
See

Table 4

Make sure that power is coming into the unit by measuring the AC or DC voltage across input power line on Terminals 12 and

13.

Note

If a fuse is blown, replace only with the same size fuse. If the fuse blows again after replacement, consult ADB

Technical Service to analyze the problem. See Section

Power Supply Board

for additional information regarding the

Power Supply board.

7.2 Receiver Frequency Setting

To set (or change) the operational frequency use the front panel ← (down) and → (up) buttons to select the frequency. Once

the correct frequency has been displayed, press the ENTER button once. After the display shows VERIFY press and hold the

enter button for five seconds to move the frequency to non-volatile memory, and move the receiver to the new frequency.

Note

The operating frequency is adjustable in steps of 25.0 KHz (0.025 MHz) between 118.0 and 136.0 MHz VHF.

The frequency will be retained if power is lost to the Radio Control Equipment.
