Lectrosonics HH Alignment Procedure page 25

Note Entering Set-up mode is not necessary if the Alternate Method is exercised.
DUT in "Passthru"
Frequency set to middle
Frequency set to middle frequency
Gainsw set to auto
gainsw=0
No audio signal at DUT input
Apply +2.0VDC, 500mA current limit in at battery contact J8 (J9 is circuit common)
Observe Battery Icon on LCD display
Using the test panel key pad navigate to the "BatMon" screen
bscale? (query battery telemetry scale setting, 26 to 80)
Press MENU/SEL button on the test panel key pad to shift from High to low Frequency on LCD screen
batcal=1 Forces battery telemetry low, note frequency.
batcal=3 Forces battery telemetry high, check for frequency shift of 3.5KHZ
Press UP or DWN button on the test panel key pad to adjust for 3.5 KHz freq.
shift
bscale=xx (set battery telemetry scale setting, 26 to
80) to adjust for 3.5KHz frequency shift
Repeat steps 40.180.40 to step 40.180.50 until no further adjustment is necessary to achieve 3.5 KHz freq. shift
Using the test panel key pad navigate to the frequency "Main" screen
batcal=0 (sets battery telemetry to normal)
Apply +2.25VDC, 500mA current limit in at battery contact J8 (J9 is circuit common)
Press Power button on the test panel key pad and hold for 3 to 4 second and watch LCD as unit powers down.
Measure current draw
Press Power buttons and hold for 3 seconds as unit powers on ON.
Measure current draw
battery icon blinking ON/OFF
3.5 KHz +/- 0.1 (3.5)
3.5 KHz +/- 0.1 (3.5)
0 to 4mA (0)
300 to 350 mA (275)
