5.6 Performance Testing
5.6.1 Transmitter Test Pattern
The Transmitter Test Pattern test is used to transmit specific test patterns at a desired frequency so
that the user can perform tests on the radio’s transmitter (see
Figure 5-10 ).
This screen contains the following fields:
• Tx Frequency:
This field selects the Transmit Frequency directly in MHz.
• Channel Spacing:
This field allows the user to select the desired transmit deviation in kHz.
• Test Pattern Type:
This field represents the type of test pattern which will be transmitted by the radio when PTT
TOGGLE button is pressed.
NOTE: Channel Spacing and Test Pattern Type fields will be grayed out while radio is transmitting.

5.6.2 Battery Reading Calibration
This alignment procedure adjusts the calibration factor used by the radio when determining the
battery voltage. Correct calibration is required to ensure valid operation of the low battery indicator.
Before starting this procedure, make sure that the radio is not connected to the PC.
1. Remove the battery and use a regulated power supply to apply exactly 6.9 V to the battery
contacts.
2. Connect the radio to the PC and read the radio (see Section 5.2: “Reading the Radio” on
page 5-2 ).
3. Click on the “Auto Calibrate” button to make the radio determine a new calibration factor.
