5. MAINTENANCE

5.1. INTRODUCTION

This section contains periodic maintenance and performance test information for the amplifier.

NOTE:

Check your sales order and equipment warranty before attempting to service or

repair the unit. Do not break the seals on equipment under warranty or the warranty

will be null and void. Do not return equipment for warranty or repair service until

proper shipping instructions are received from the factory.

5.2. PERIODIC MAINTENANCE

Periodic maintenance requirements are listed in Table 5-1. Table 5-1 also lists the intervals at

which the tasks should be performed.

WARNING:

Wear proper eye protection to avoid eye injury when using compressed air.

Site Conditions

6 Months Inspect signal and power cables for

frayed insulation and proper attachment.

Check RF connectors to make sure that

they are tight. Inspect the lightning

protection system and ground at the site.

5.3. CLEANING AIR INLETS/OUTLETS

The air inlets and outlets should be checked every 30 days and cleaned if necessary. If the

equipment is operated in a severe dust environment, it should be checked and cleaned more

often. If dust and dirt are allowed to accumulate, the cooling efficiency will be diminished. Using

either compressed air or a brush with soft bristles, loosen and remove accumulated dust and dirt

from the air inlet panels.

Check that the fan is running smoothly. A slow running or noisy fan may indicate an imminent fan

failure. Replace immediately with a similar to insure long term reliability. Heat is one of the

biggest factors in reducing the reliability of your amplifier. Make sure the fan has access to cool

and clean airflow within the rack.
