OPERATING MANUAL – 525N - 30 OLTS

Boot, Housing and Power Options

Removing/Installing the Rubber Boot

The 525N Series optical test set is fitted with a rubber boot that pro-

vides impact and shock protection during use. This rubber boot incor-

porates a swing-out stand, permitting convenient viewing of the dis-

play when the instrument is used on the benchtop.
The rubber boot must be removed to access the battery compartment

cover on the back of the instrument housing. To remove the boot, do

the following:

1. Grasp the boot in both hands and gently peel back the sides

starting from the top.

2. Press the back of the instrument through the rectangular hole in

the boot to pivot it forward.

3. Pull the instrument away from the boot.

Installation of the boot is the reverse of removal. Make sure the

instrument is seated snugly in the boot before use.

NOTE: To prevent damage from shock or impact, do not use the instrument
without the boot in place.

Removing/Installing the Battery Cover

The battery compartment is sealed by a plastic cover secured by two

Phillips screws, which must be removed for access. To open the bat-

tery compartment, do the following:

1. Remove the rubber boot as described

in the preceding section.

2. Lay the instrument display-side down

on a soft surface, such a towel, to pre-

vent scratching of the front panel.

3. The two screws securing the battery

cover will now be visible. Remove

both screws by turning them counter

clockwise using a #1 Phillips screw

driver. Put the screws in a safe place.

4. The battery cover can now be lifted away from the instrument

housing. Gently pry up on the bottom of the cover. DO NOT

USE A METAL TOOL TO PRY OPEN THE COVER.

Installation of the battery cover is the reverse of removal. Take care

not to overtighten the screws securing the battery cover or damage

may result.
