To get reproducible results, the device is evaluated in the TEM cell. Place the completely assembled receiver with its display upside down and its antenna in direction to the signal feeding (as shown below). The test is configured to prove whether the DV09A possesses the following call sensitivities: Swissphone Telecom... - Page 8 3 of 4 calls at -102 dBm (TEM cell, order no.: 0352000 "free field measure box TEMCELL 1700") The limiting values of the sensitivity have to be reached at the lower as well as at the higher test frequency.

This is about the tuning of the PLL reference oscillator. In contrast to VHF the value for UHF is not fixed. It must be corrected because the quartz is temperature dependent. 1. Turn on or off temperature compensations Turn off the temperature compensation first before retuning the reference oscillator.
