I have a polar a3 watch / hrm and tried to change the battery. I think I have every oriented correctly but it does not wake up with the new battery. Are there pictures available (say an exploded view of...
Polar A3 Watch Battery Replacement
Read all instructions first.
Once you have the back of the watch off, examine the watch and dry run the instructions in your mind. Prepare for trouble! So you can avoid it!
Work in a well lit, spacious area and NOT over a shag rug.
You\'ll need a set of jeweller\'s screwdrivers, with a couple of small philips (hex) heads and a large plate for itty bitty bits and pieces. And a Black Sharpie.
Carefully remove the back casing of the watch by removing the 4 screws. PLACE EACH INFURIATING LITTLE SCREW IN A SECURE PLACE OR SURE AS S&S, YOU WILL LOSE THEM!
Upon removing said back, you will see the battery and a half-moon shaped retaining clasp, which holds the battery in place. This clasp is narrow at one end and square at the other. You WILL also notice that each end of half-moon clasp (HMC) slips under the main metal retaining casing of the battery to hold the battery in place. Examine this carefully, and keep a mental picture of this in your mind. This is the end result that you must produce again.
Notice the orientation. Take a Black Sharpie and make a dot on the square end of the HMC and on the watch compartment, so as not to inadvertently switch the ends. (It won\'t install, but this is a nice way not to have to have a panic if you forget the orientation.)
Digital pictures are cheap. Take a picture if you\'re not the most gifted in do-it-yourself stuff. Learn from my mistakes, my young padewans!
In the half-moon clasp, you\'ll see a small circular opening at the narrowing end.
Insert the screw driver and GENTLY pry back on the screw driver, so as to warp the piece of metal--into a U shape--such that the end--where the hole that the screw driver is in--slips out from underneath the main metal casing.
BE VERY CAREFUL HERE!
THIS IS WHERE THE CURSING STARTS AFTER YOU HEAR THE QUIET "FO-ING!" AS IT FLICKS AWAY, NE\'ER TO BE SEEN AGAIN, IF YOU\'RE WORKING OVER A SHAG CARPET.
IF THIS OCCURS, SEARCH FRANTICALLY. GOOD LUCK.
For those of you who have managed to remove the one end of the half-moon clasp, gently pull the HMC, with the screwdriver in the hole, to remove it from the position.
Place HMC on plate with itty-bitty-screws.
There is a small circular indent on the edge of the battery compartment.
Place the screwdriver tip in this and gently pry up to remove the battery.
Replace the old battery, with the new one. (Set the old one aside, far aside. You think I\'m kidding? Trust me... It happens. For those of you who did not head my warning, you might want to start again! Especially those that didn\'t check to make sure the watch was running!)
Take the HMC, set it on top of the battery in the original orientation and with the screw driver, gently press down on the square end--compressing the HMC and battery--such that you are now able to slide it, the square clasp end, under the circular compartment metal lip, that the battery fits into. Excuse my dangling participle and grammar.
The other end--the narrow end--of the HMC should be sticking up.
Run through these steps in your mind to set up the best approach for yourself.
Orient the watch so you are comfortable working with it.
Insert the tip of the screwdriver end into the hole in the narrowing end of the HMC, and gently, press back on the screw driver, so as to warp the HMC, and...
The screw driver, in the hole, should provide enough friction that it doesn\'t slide in the hole. Do not insert the screw driver too far into the hole, or you will not be able to maneuver the narrow end of the HMC, guiding it with the screw driver, back under the lip of the compartment, as it was originally.
... slide the narrow end under the lip.
If all has gone well, you should be able to turn your watch over and it will be displaying...
Gobbledy-gook or nothing at all! And you\'re screwed!
Not so fast my young padewans!
Most likely, you are seeing gobbledy-gook.
This is good. It means the watch battery swap has worked.
Turn the watch back over and you will see a itty-bitty copper finger, protruding from the battery compartment edge, out over the battery.
Gently press down on this, so it touches the batter, using the screwing driver, to reset the watch.
Turn the watch over and it should be displaying the basic reset display, flashing 12HR.
If not, the battery is not seated properly.
Remove the battery and begin again.
Check to make sure you have a new fresh battery.
Otherwise, carefully install the back cover with the itty-bitty screws. (IBS)
When screwing in the IBS do not speed them in, by rolling the screw driver in your fingers against your palm.
Insert the screw, (I use fingers, you may want to use tweezers.) and place the screw driver into the head of IBS and orient the screw to a perpendicular position, then turn the screw counter-clockwise in order to set the threads, then turn 1/2 turns, clock-wise, reseating your fingers, to provide firm pressure when screwing in the IBS.
Start in one corner, and screw in the screw so that it is just loose to the case. Then do the other, opposite corner similarly, then the corner to the side (pick one...) then the opposite corner. There\'s only one left at this point...
Make sure the case is seated properly, and that you\'re satisfied with everything (No spare parts kicking around!) and repeat the proceedure, tightening the screws in the criss-cross pattern.
Reset the watch as per instructions for time and date and knock yourself out.
