PHONE RF FIELD TEST

Perform this test BEFORE conducting the screen replacement to confirm the phone is

working properly and repeat after screen replacement is complete to confirm the

phone is properly working.

Once repairs are completed Signal Strength must be compared to the original

readings. Strength of signal must be within -10 dBm of the original reading at the

same phone location. Example: If first reading is -91 dbm, new reading cannot be

greater than -101 dBm. Readings moving up show a stronger strength and are

acceptable. Example: From -91dBm to -81dBm. -150 dBm is a no signal

indication.

Note: Clean Work area of all or any debris after Repair.
