4.7.3  GPS I (Interface) connection 
  The AquaFix™ 406 GPS P-EPIRB (P/N 2797.2 and 2797.4) comes standard with an Optical GPS 
data interface with LED (Hard wire connection to you onboard GPS NEMA 0183 output). Connect 
the serial port adapter to your external GPS connection data cable. Connect data plus and minus 
leads to your NEMA 0183 output wire (consult onboard GPS manual for proper wiring instructions). 
The ONLY reliable way to hook up your marine electronics is to solder the leads together, cover the 
solder connection and exposed wire with liquid electrician’s tape, and then slips a section of heat 
shrink over the outside and seals it in place.
 If the holster is on the P-EPIRB, align the two tabs on 
the bottom of the interface with the holes in on the holster directly above the interface port (see figure 
6). Push down and turn to secure the interface cable to the holster. If the holster in not on the P-
EPIRB simply hold the interface head on top of the interface port with your finger (see figure 7).  
SECTION 5 – P-EPIRB Holster 
5.1  The AquaFix™ comes standard with a protective holster that will help protect your P-EPIRB from 
damage. To install the holster, deploy the antenna and slide antenna through the open hole located 
on the left side of the holster. Slide the holster to the base of the P-EPIRB so that the open antenna 
hole is flush with the side of the P-EPIRB. Close the back of the holster around the back of the P-
EPIRB and clip into the front of the holster. Once secured, wrap the  antenna around the base of the 
holster and clip into antenna slot on the top right side of the holster (See figure 8). 
Note: Use extreme caution; do not apply the holster over the antenna. In an emergency it is critical 
that you deploy the antenna. If the holster is covering the antenna you will not be able to deploy 
properly.

5.2  The AquaFix™ holster has been designed to accommodate your extreme adventures. You can 
secure your P-EPIRB directly to backpack webbing straps or belts to ensure the P-EPIRB is close at 
hand. Ensure the P-EPIRB is secured firmly and is protected before heading out to avoid damage or 
loss. ACR recommends that you secure your P-EPIRB someplace that is easily accessible in case of 
an emergency for rapid activation. 
Note: Use care when attaching items to your P-EPIRB. Clipping attachments, carabineers, rope, 
webbing, etc. will all add weigh and can affect the buoyancy of the P-EPIRB. Your P-EPIRB may 
not float if items have been attached to it.
