DISMANTLING AND RE-ASSEMBLY

Dismantling

1. Use the bladed screwdriver to loosen the four captive

screws that secure the Front Bezel and/or Rear Cover
Assemblies (depending on which component is being
replaced) and remove the cover(s).

2. Remove Power Supply and/or Input PCB Assemblies

by unscrewing the two Phillips screws and unplug the
assemblies from their connectors.

3. Remove

Microprocessor/Display PCB Assembly by

unscrewing the four Phillips screws and unplug the
keypad cable by lifting the locking arms on the side of
the connector and remove the cable from the
connector.

4. Remove the cable hubs by screwing the retaining nut

and removing the hub from the Shell Assembly.

Reassembly

Check that the gaskets are not damaged and have a thin
layer of silicone grease. If the gaskets are damaged,
replace gaskets.

1. Install the Microprocessor/Display by securing the

assembly with the four Phillips screws and installing
the keypad cable into the connector and locking it into
place by pushing down the two locking arms on the
side of the connector.

2. Install the Power Supply and/or Input PCB

Assemblies into their respective connector and secure
the assemblies with the two Phillips screws per
assembly.

3. Attach cable hubs by installing the gaskets onto the

hubs and insert the hubs into the ports in the Shell
assembly. Secure the hubs by tightening the nut onto
the hub threads.

4. Install the Front Bezel and/or Rear Cover Assemblies

and secure by tightening the four captive screws per
assembly using a bladed screwdriver.

Caution.

Dismantling and reassembly should not be
carried out on site because of the risk of
damage to components and printed
circuits. The dismantling and reassembly
procedures should be carried out in the
listed order to avoid instrument damage.

Warning.

Substitution of any components other than
those assemblies listed in this section will
compromise the certification listed on the
transmitter nameplate. Invalidating the
certifications can lead to unsafe conditions
that can injure personnel and damage
equipment.
