Garmin 305 业主指南

PPENDIX

The heart rate monitor contains 

a user replaceable CR2032 

battery. Be sure to dispose of old 

batteries properly. To replace the 

battery, locate the circular battery 

cover on the back of the heart 

rate monitor. Use a coin to twist 

the cover counter-clockwise until 

it is loose enough to remove. 

Remove the cover and replace 

the battery. Be careful not to 

damage or lose the o-ring gasket 

on the cover. Then use a coin to 

twist the cover back into place.
