    • McMurdo Fastfind Plus – all variants • McMurdo Max and Max G – all variants • NOTE: The method of distinguishing the various versions of PLB is by serial number. This is located on the label underneath the battery pack and also in the User Manual supplied with the unit.

  • Page 6: Servicing Equipment

    All agents are obliged to possess specialised equipment to ensure that PLBs are serviced correctly. A message reader (ARG5410 or equivalent) is mandatory. Equipment: Message reader PLB programming kit (FPROG – McMurdo P/N 85-923/924) Thermometer (required for leak testing) Hand tools: Antenna rewind key (McMurdo P/N 85-753)

    De-activating a live PLB Press and hold the OFF/Test button; wait for the red LED to extinguish. If the LED does not extinguish, remove the battery (refer to section 3.8) and return the PLB to McMurdo for investigation. PLB service manual Issue 4...

  • Page 9: Assessment

    Servicing agents are reminded that it is their responsibility to ensure that the procedures are followed, that only McMurdo approved parts are fitted, and that good practice is observed. False alarms caused by inadvertent activation must be avoided. We recommend that PLB testing is only done in self-test mode to avoid false alarms.

    Commercial in confidence 85-909 3. MAINTENANCE PROCEDURES 3.1. Inspection Tamper seal Check tamper seal is intact. If seal is damaged or is non-standard in any respect, battery state must be considered suspect. Contact customer to confirm any history of PLB activation. Plastic damage Check that the flip lid is present.

    Commercial in confidence 85-909 3.2. Functional tests Self test Slide a finger under the red anti-tamper cover, press and hold down the OFF/Test button The red LED should come on After approximately 10 seconds the green light must flash 3 times and the buzzer must sound three times to confirm self-test has passed.
  • Page 14 Commercial in confidence 85-909 GPS Test The GPS system should be tested only when its operation is suspect. Because of the time required to obtain a GPS position, it is necessary to operate the PLB in the live transmission mode, and hence it must be contained in a screened enclosure for the duration of this test.

  • Page 15: Message Read

    Commercial in confidence 85-909 3.3. Message read NOTE: When the antenna is not deployed, the transmission power is greatly reduced. The Message Reader must be very close to the PLB to detect this weak signal. Use a "Message Reader" to verify the unique ID. A typical instrument is the ARG5410, which is used here to describe the process.
  • Page 16 Commercial in confidence 85-909 Common problems with message read Audio tone If not heard then reduce range from 1m to 0.3 m to help. Frequency If outside limits, repeat self-test several times to provide a warm-up. Bad frame/Data error/ This error message occurs if the Reader fails to Self test bad/ synchronize.

    6. Remove PLB from water, wipe thoroughly dry. 7. Replace the flip-top lid Any escape of bubbles indicates a fault. Return the PLB to McMurdo for servicing. 3.7.

NOTE: Later –20 °C battery packs are larger than the original versions; this modification enables the PLB to float when fitted with the later battery pack.

  • Page 19: Antenna Rewinding

    Commercial in confidence 85-909 WARNING: The ‘O’ rings and lanyard must be fitted correctly, otherwise the PLB will not be watertight. Battery disposal Hazardous chemicals Use gloves Lithium battery packs should be discharged slowly, then disposed of through an approved environmental disposal agent, or in accordance with local regulations.
  • Page 20 Commercial in confidence 85-909 Rewinding the antenna Once activated, the PLB has the antenna extended. The tamper cover, with seal and retaining pin, is usually absent – in any case, a tamper cover should NOT be re-used. Inspect the antenna for damage, such as cracks, creases or delamination of the coating. Ensure that the antenna is fit for re-use.
  • Page 21 Commercial in confidence 85-909 5. Place the cover in position and engage the retaining pin in the holes in the antenna. Keep pressure on the tamper cover to prevent it springing off, then withdraw the winding key. 6. Fit the screw to the tamper cover and tighten it to a torque of 25 cNm.
