1. Description
The "McMurdo Marine R3' Radio is a rugged portable handheld transceiver
designed for ship to aircraft emergency communication. It operates at the
primary and auxiliary aeronautical emergency frequencies 121.5 and 123.1
MHz, The internal primary single cell lithium battery combines a mlnlmul’l’l 0!
replacement cost and typically 24 hrs of normal operation (90% standby.
squelched receiver,5% receive audio. 5% transmit).
A minimum of controls makes the operation simple and safe, even by unskilled
persons. The tin-breakable leaf antenna unfolds automatically before
operation. The metal housing provides optimum electrical performance
(EMC/EMI) and the best mechanical protection.
The transceiver complies with the TS 101389 v1,1.1 (1997-09) technical
specification.

The antenna must be fully extended helore operation The transceiver Is turned
on by the irequency selector located at Ihe top of the transceiver Move the
selector to the left for 1215 MHz (the primary aeronautical distress frequency)

4. Maintenance
4.1 Battery replacement
Turn off the transceiver Open the battery cover by removing the four screws
Remove and unplug the battery. Replace the new battery and reassemble the
cover Date of expire must be noted at the back side of the transceiver (usually
four years after replacement). Avoid short-circuiting the battery Old batteries
should be disposed as special waste
4.2 Fuse
The negative battery circuit of the transceiver is fused for security reasons, This
fuse will blow if the positive terminal of the battery by accident is shorted to
ground The fuse is located on the printed circuit board, at the let hand side of
lhe battery Fuse rating 3A, size 1206 Fuse typeFiZOGBSROOFWTR (AVX) or
equ To be replaced only by Authorised persons
4.3 Passivation of batteries
If the radio appears not to be working, this may be due to an effect known as
‘Passivaition‘ which affects the batteries as a result of being in storage, along
time This means ifthe Radio is not used for long periods, this effect may be
observed. The batteries will automatically recover from this state after a few
seconds of use To overcome this effect, the Radio will need to be
switched ‘ on and off‘ a few times (possibly 5 to 6 times) to break through
the pauivation layert
4.4 ESD
Use an Electra-static Discharge - safe work station during battery replacement
and other service
