5、AL / SYSTEM SET-UP Model If the D key is pressed while CLONE LOCK is displayed, the Read authorization password input screen (INPUT PASSWORD) is displayd. If one of keys 0 to 9 is pressed while INPUT PASSWORD is displayed, the pressed number is displayed on the LCD. Each press of the key shifts the

6、display in order to the left. When you enter the password and press the A or key, “CLONE MODE” is displayed if the entered pass- word is correct. If the password is incorrect, “CLONE LOCK” is redisplayed. How to enter the password using the Side2 and Side3 keys (K2 and K3 models); If the D key is pr

7、essed while CLONE LOCK is displayed, the Read authorization password input screen (INPUT PASSWORD) is displayd. If the Side2 key or Side3 key is pressed while INPUT PASSWORD is displayed, the number (0 to 9) flashes on the LCD. When you press the D key, the currently selected number is determined. I

8、f you press the A key after entering the password in this procedure, “CLONE MODE” is displayed if the entered password is correct. If the password is incorrect, “CLONE LOCK” is redisplayed. 4. Power on the slave transceiver. 5. Connect the cloning cable (part No. E30-3325-05) to the universal connec

9、tors on the master and slave. 6. Press the Side1 or A key on the master while the mas- ter displays “CLONE MODE”. The data of the master is sent to the slave. While the slave is receiving the data, “PROGRAM” is displayed. When cloning of data is com- pleted, the master displays “END”, and the slave

10、auto- matically operates in the User mode. The slave can then be operated by the same program as the master. 7. The other slave can be continuously cloned. When the Side1 or A key on the master is pressed while the mas- ter displays “END”, the master displays “CLONE MODE”. Carry out the operation in

11、 step 4 to 6. Notes: Can not be cloned if the password (over write password) is programmed to the slave. Model Name and Market Code must be same to clone the transceiver. However, it may be unable to clone the transceiver depending on the enhanced features settings. (Refer to the FPU for the enhance

12、d features details.) 8.

Memory Circuit

39、 Memory circuit consists of the CPU (IC5) and a flash memory (IC6). A flash memory has a capacity of 16M bits and Fig. 8PLL block diagram T/R IC414 V-assist TX: 272348MHz RX: 371.9447.9MHz RHE PCS DAT CLK LE DAT CLK IC304Q314D101 to pre-pre-drive LPFVCO 1/2BUFFSW ULCV IC5 IC303Q312D210 to 1st mixer

40、(Q101) (IC202) CPU PLL LPF BUFFSW MOD X301IC411 VCXODAC TK-5210 17 CIRCUIT DESCRIPTION contains the transceiver control program for the CPU. It also stores the data for transceiver channels and operating param- eter that are written by the FPU. This program can be easily written from an external dev

41、ices. The EEPROM (IC2) stores the last channel data, the scan on status, and other parameters. Flash memory Note : The flash memory stores the data that is written by the FPU (KPG-95D), and firmware program (User mode, Test mode, Tuning mode, etc.). This data must be rewritten when replacing the fla

42、sh memory. EEPROM Note : The EEPROM stores tuning data (Deviation, Squelch, etc.). Realign the transceiver after replacing the EEPROM. Real-time clock The clock function is based on real-time clock IC (IC1). When the power supply is off, it is backed up by an internal secondary lithium battery 6-2.

43、LCD (K2 and K3 models only) The LCD is controlled using the bus lines on the connector (CN604) of the control unit (X57 B/5). It corrects the LCD contrast voltage using IC704. The voltage corresponding to the temperature is sent to pin 3 of IC704 from the CPU (IC5) according to the temperature measu

44、rement results using a temperature IC (IC4). 6-3. Temperature Detection Circuit The temperature detection circuit detects the temperature using a temperature IC (IC4) and corrects the thermal characteristic change of the squelch or LCD. 6-4. Key Detection Circuit Keys are detected using three shift

45、registers (IC701, IC702, IC703). The KIN signal that is normally pulled down goes high when any key is pressed. 6-5. Low Battery Warning The battery voltage is divided using R15 and R16 and is detected by the CPU (IC5). When the battery voltage falls below the voltage set by the Low battery warning

46、adjustment, the red LED blinks to notify the operator that it is time to replace the battery. If the battery voltage falls even more (approx. 5.8V), a beep sounds and transmission stops.
