EX7100 Technical Manual - Module Descriptions

The module contains semi-conductor components that are

sensitive to electrostatic damage.

Electrostatic sensitive devices should only be stored and

transported inside electrically conductive static shielding

bags. Fault finding and module replacement must be

performed at “electrostatically safe work stations” where the

work bench surface, soldering iron and the operator are all

earthed to prevent the build up of harmful electrostatic

charges.

Accessing the UHF Receiver Module

To gain service access to the Receiver module, remove the bottom cover as per Section

6.1.

Diagnosis

With the unit de-powered, check the receiver module visually for signs of damage such

as burnt tracks or components. Check that all connectors are fully mated. If no damage

is apparent, apply power and follow the steps outlined in Figure 7.24 overleaf
