Adjustment
Point
TP15 1. Configure the DECT tester (CMD60) as follows;
<Setting>
· Test mode: PP

2. Execute the command "testmode".
3. Execute the command "regcmd60"
4. Initiate connection from DECT tester.
5. Execute the command "openaudio".
6. Confirm that the value of EEPROM address "34A" is "02". (If the value is not
"02" (by User), set "02" and power off and power on, and return to clause 2.)
