Replaced the battery on my forerunner 50 watch

Just got off the phone with Jason at Garmin tech support. Very helpful. Walked me through the steps to replace the battery. Basic steps are 1. get the 4 screws off 2. With a tiny screw driver lift up the pry bar holding the battery in place. The white adhesive tab will come off with it. 3. save the transparent plastic sheet and note the stenciled cut outs (required to prevent contact) 4. remove the old battery 5. drop in the new. 6. out the transparent plastic sheet aligning the cut outs carefully. 7. place the pry bar back on and nudge it back into the ends. 8. Place the white strip adhesive back on to hold the pry bar in place. 9. put the back cover on making sure to align the little notch on one end with the notch in the base of the watch. 10. put the 4 screws back on. 11. You should have the watch functioning again. Was not so difficult - if I could do it with my presbyopia i'm sure anyone can do it.

BTW, the watch had lots of problems pairing up with the HRM after replacement. Jason helped me out with this too. Need to desensitise the HRM by 1. remove the HRM battery 2. flip the battery backwards and close the battery compartment for a minute 3. Reopen the battery compartment and put the battery in with the "Lithium" sign facing up. 4. Close the battery compartment. 5. Pair it now with the watch. Hope this helps!
