obstructions.

Eliminate any possible

interfering devices (micro-

waves) between the radio

module or carrier assembly

and your handset.

Turn off or unplug nearby

modem) to see if it is

causing interference. If it

is, make sure it is on a dif-

ferent power line or move

it further away from the

handset, radio module, or

quality readings are low,

look for a newly installed

radio device nearby.

Remove it or move your

module.

■

Place the handset in

determine sound clarity as

described on page 10. If
