Pressing PF1 while the 55 seconds test is in progress stops the test. At the end of test transmission, BDLCPD operation returns to normal and the RX LED lights in green (monitoring normal transmitter activity).
3.2.1.4 3.2.1.5 LEDs and Indications RS-232 LED Function Selection The PF 1 button is used to select the RS-232 display mode as follows: • If pressed ONCE (do not hold pressed): - Clears Alarm indications - CK LED stops flashing for 2 seconds - During this time, one or all of the RS-232 numbered LEDs (see Figure 13) will light. If one LED lights, it denotes the port to which the subsequent display applies. If all numbered LEDs light, it denotes that the normal 3-port display mode is active.
3.2.1.5.2 RS-232 Port Indicators Blinking slowly (1 cps), indicates the parameters contents of the flash memory have been corrupted. The unit automatically loads its set of factory default parameters and starts beeping at 20 seconds intervals. The RS-232 LEDs normally indicate port activity on the port selected. See section 3.2.1.4 above for instructions for selecting display mode. May also indicate DSP-modem initialization has occurred CM FR FT RD TD 1 2 3 3.2.1.5.

5.1.3 Channel Selection via DIP Switches The backplane-mounted DIP switch settings override the default channel programmed by PGM800Win. To select a channel, set the appropriate DIP switch or switches to “OFF” to make the binary count total the channel number you want. Set all other switches to “ON”. To set a default channel via the software, all DIP switches must be set to “OFF” (i.e. 00000000). It is recommended to set both SW1 (RX) and SW2 (TX) to the same settings on both back plane boards.
5.2 Series II Radio Tuning This section covers some basic Series II base station modules radio tuning and verification for: - VHF (T83x-xx-0200), - UHF (T85x-xx-0250) and - 800 MHz/900 MHz (T88x-xx-0200). Note: Usually, this section is not done unless called for in section 5.1 “Series II - Radio Programming” or in Table 9 “Checklist B” (General).
5.2.2 Receiver module (T885-xx-0200, T855-xx-0250 & T835-xx-0200) Note 1: Refer to Figure 27 (T885), Figure 29 (T855) and to Figure 31 (T835) for locating tuning controls. Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will flash indicating that it needs re-tuning. Warning, The LED will also flash when the unit is in setup mode while connected to the PGM800win program. 5.2.2.
5.2.2.3 Front-End Alignment 1. IFR COM120B settings: a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel frequency c) Select and turnon GEN2 d) Set the FM Deviation to ±3kHz (full channel) or ±1.
5.2.2.5 RSSI Adjustment - Caution: mis-adjusting RSSI may reduce the ParagonPD's Parallel Decode (PD) performance. - BDLCPD must be connected to the radio backplane during this process. 1. T885-xx-0200 (800/900 MHz) and T855-xx-0250 (UHF) receivers: - Apply an on-channel signal from the RF generator at a level of -110 dBm modulated by a 1 kHz tone at a deviation of ±3kHz (full channel) or ±1.5kHz (half / NPSPAC channel). - Adjust RV 345 (RSSI level) for T885, RV320 (RSSI level) for T855 to give 2.

Multiple channels (adjusting as shown for single channel above): 1. T881 (800/900 MHz) Adjust the VCO loop to 10V using the middle frequency channel. 2. T857 (UHF) Adjust the VCO loop to 10V using the middle frequency channel. 3. T837 (VHF) Adjust the VCO loop to 9V using the middle frequency channel. All channels should lie within the upper and lower limits of 16V and 3V respectively for the T881 and T857 or within 13V and 5V for the T837.
6. For multi-channel unit, select the highest frequency channel. Transmit a square wave by pressing PD the BDLC ’s PF1 button and following the procedure outlined in section3.2.1.3. Record deviation again. 7. The difference in deviation between the two channels should be less than ±300Hz. If not, readjust IC220 to "average" the square wave shape on both channels until the spec is met. 8. To confirm the adjustment, select the active, or the lowest frequency channel.
5.2.4.2 Forward Power Alarm Level (Optional setting) 1. Power up the PA and adjust front panel power control so that the output power is at the alarm level required, usually 20% lower than nominal value (e.g. 40W if the PA normally operates at 50W). 2. Adjust the forward power alarm set (T889 or T839: RV101and T859: RV48) so that the forward power alarm LED lights. 3. Adjust front panel power control for the normal operating power level 5.2.4.3 Reverse Power Alarm Level (Optional setting) 1.
3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply current, but do not exceed a maximum drop of 0.5A per control. 4. Check that the supply current is <22A for 100W output power. Note: These control settings are normally very close to minimum supply current. If the current is reduced too far, maximum power output will drop and 2f rejection may degrade. 5.2.5 (TPL) LMS series Power amplifier (PA8-2BF-LMS) (890-960 MHz) Note: Refer to Figure 26 for parts location. - 5.2.5.
b) Toggle the front panel switch until the top line of the display reads RFL PWR. c) Key the transmitter T881's Exciter Carrier button. d) Adjust TPL's VR7 so that the front panel meter is in agreement with the calibrated power meter. 5.2.5.7 Reverse Power Alarm Level a) Connect an unterminated 3dB pad to the PA output (e.g. 3:1 VSWR). e) Key the transmitter T881's Exciter Carrier button.
