Servicing Equipment - mcmurdo C1 S-VDR Service Manual

1.3 Servicing equipment

All agents are obliged to possess specialised equipment to ensure that S-VDRs are
serviced correctly. A message reader (ARG5410 or equivalent) is mandatory; service
agents in countries where RF power measurement is required must also have a
suitable RF power meter and attenuators.
Equipment:
Message reader (eg Sartech 5410)
Programming Kit
PC computer and printer
Static safe work area with operator wrist strap
Magnet
Conductive metal plate or shorting link
Screened enclosure
Test Fixture
Handtools:
Calibrated torque driver (60-85cNm) with attachments:
7mm A/F (M4) socket
Small cross-headed screwdriver
Medium Cross-headed screwdriver
11mm A/F box spanner or socket
10mm A/F spanner
19mm A/F spanner
Antistatic precautions
The electronics sections of the S-VFR are sensitive to electrostatic discharge (ESD)
which can cause immediate or hidden long term damage. It is important that the
PCBs are only handled under suitable antistatic conditions.
Ideally, a fully grounded workstation, which has conductive surfaces to avoid the
build up of static charge, should be used.
As a minimum, the operator must be connected to a good earth point through a
resistance of 1Mohm. This is usually achieved by wearing a suitable wrist strap.
