A new battery pack must be fitted when the expiry date has been
reached. Only use branded battery packs designed specifically for the
Fastfind and Fastfind Plus products. Do not remove and replace the
battery pack unnecessarily: this may jeopardise the integrity of the O-ring
seals which prevent water ingress around the battery connections
between the battery pack and the PLB. To change the battery pack, refer
to the instructions supplied with each battery pack.

Service
The PLB contains no user-serviceable parts. It must be returned to a
dealer or Service Agent if it requires service.
A list of dealers and service Agents is on the McMurdo web site,
www.mcmurdo.co.uk, and on the McMurdo Pains Wessex site,
www.mcmpw.com
When the PLB is returned by post, if possible the original packing should
be used. Postage must be paid. Ensure that the name and address of the
owner is enclosed with the PLB.
Verification
After a battery change, or alternatively at intervals of approximately 5
years, it is recommended that the PLB is taken to an Approved Service
Agent for calibration checking. The Service Agent possesses test
equipment which verifies the performance and programming of the PLB;
this testing is rapid and involves no disassembly of the PLB.
