procedure.
Equipment:
Message reader
Screened box
Leak testing equipment (SBM testing only)
GPS repeater (SBM testing only)
Static-safe work area with operator wrist strap
Multimeter with voltage and resistance scales
Programming kit :
82-950A Light pen
82-951A EPROG5 (McMurdo variant)
Bar magnet or manual bracket with incorporated magnet
Shorting link for sea switches
Battery discharge load (made on-site as required)
Handtools:
Calibrated torque driver (0.6 Nm) with attachments:
7mm A/F socket (M4)

Large cross-headed screwdriver
Antistatic precautions
The electronics section of the EPIRB is sensitive to electrostatic discharge (ESD) which
can cause immediate or hidden long term damage. It is important that the PCB is 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.
