Installation / Setup
The installation section for the VHF Synthesized FM Two-Way Portable Radio TK-230/230(SC) includes the following highlights:
1. Installation of Options:
– Top panel replacement involves removing R107 to enter the 100CH mode, inserting the ROM supplied with KCH-2 into IC8, and soldering it. Data is written using a ROM writer.
– For KDM-4/KDM-4(A), replace the front panel and adjust DTMF DEV with the variable resistor.
– KCT-1/2 and KCT-3 involve specific sections for writing data and adjustment.
2. Changing the Number of Channels:
– Jumper resistors R106 and R107 on the control unit (X53-3210-XX) are changed to select 10, 20, or 100 channels.
3. Mounting the EEPROM (100 channels only):
– Insert the EEPROM packaged with the KCH-2 into the IC8 socket of the control unit and solder it.
4. Replacing the Top Panel:
– Involves removing screws, desoldering and pulling out leads, and inserting the 100 channel top panel (KCH-2), followed by reinstallation of leads and connectors.
5. Setting the Channel Switch Stop Position:
– The channel switch stop position can be changed by adjusting the mounting position of the channel stop.
6. Precautions:
– When disconnecting or connecting external devices like SP/MIC (KMC-11) and KCT-3, ensure the radio power switch is off.
These steps are essential for setting up and installing the TK-230/230(SC) radio system.
