6. Additional Information on EDGE Troubleshooting
Note! EDGE mode troubleshooting differs slightly from basic GSM troubleshooting.
1. Establish connection to the phone normally (see GSM850/1800/1900 trouble-
shooting instructions).
2. Select product from the menu: File -> Choose Product -> NHL-12.
3. From the toolbar, set operating mode to “Local”.
4. Activate the RF Controls window from the menu: Testing -> RF Controls.
In the RF Controls window:
• Select Band “GSM850” or “GSM1800” or “GSM1900” (Default=”GSM850”).
• Set Active unit to “Tx” (Default=”Rx”).
• Set Edge “On” (Default=”Off”).
• Set Operation mode to “Burst” (Default=”Burst”).
• Set Tx data type to “Alternate PN9” (Default=”All1”).
Note! In EDGE tuning, set data type to "All 0's". If you are using "Alternate PN9", you need
to tune power levels 1dBm lower than the target levels.
• Set Rx/Tx channel to 190 on GSM850 or 700 on GSM1800 or 661 on GSM1900
(Defaults).
• Set power level to 8 (Default = 19) on GSM850 or to 2 (Default = 0) on GSM1800
or GSM1900.
NOTE! For GSM850 EDGE power levels 5, 6 and 7 are not in use and for GSM1800&1900
EDGE power levels 0 and 1 are not in use.
