WARNING: lf the PEPIRB has been used in an emergency, the battery pack
must be replaced. lt is advisable to return the PEPIRB to MPWI for a
complete service
Before use
lf the PEPIRB has not been examined for more than 1 month, check the
battery expiry date. Run the self-test. Examine the PEPIRB for any signs of
cracks or other damage.
After use
lf the PEPIRB has not been activated, clean it using fresh water, wipe dry
and examine for any damage. Store in a cool dry place until next needed.
lnadvertent Activation
lf you accidentally damage the tear-off cover or the tamper seal or if you
deploy the antenna, the PEPIRB should be returned to MPWI for repair and
examination.
Battery Packs
The PEPIRB is fitted with a battery pack which can be changed by the user.
The battery pack provides 24 hours continuous operation at a minimum
temperatuie of -2O"C (-4"F). With this pack fitted, the PEPIRB complies with
COSPAS-SARSAT Class 2 PEPIRB requirements.
A new battery pack must be fitted when the expiry date has been reached.
Only use branded battery packs designed specifically for the Fastfind
product.
Do not remove and replace the battery pack unnecessarily: this may
jeopardise the integrity of the o-ring seals which prevent water ingres_s
around the battery connections between the battery pack and the PEPIRB.

Method
1. Remove the battery retaining screw and detach the battery. lf
appropriate, dispose of this battery in accordance with local waste
disposal regulations
2. Fit the two 'O' rings to the battery connectors. lt is recommended to
fit these to the pillars, rather than placing them in the recesses of the
battery pack, but either method may be used as desired
3. Assemble the battery pack to the PEPIRB, taking care that the 'O'
rings stay in place.
4. Fit the lanyard securing tag (the battery screw block - shown as O
in the left illustration below) lt is essential that this part is fitted,
as it forms part of the PEPIRB sealing system.
5. Fit the screw to retain the battery pack, and tighten it securely; a
torque in the range 0 15 to 0.18 footpounds (38 to 46 ounce-inches)
is correct
