TABLE OF CONTENTS 1. 2. 3.
3-1. 3-2. 3-3. 3-4. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. · Unleaded solder melts at a temperature about 40 °C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 °C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! · Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. · Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

EEPROM INITIALIZE MODE
Procedure: 1. Turn on the power to place the set in the standby state. 2. Press the [BAND/SET], [LIGHT] and [MODE/FREEZE] keys simultaneously for 5 seconds, or short the TP116 (KS0) and TP117 (KR3) on the key board. 3. When the EEPROM initialize mode is activated, the BEEP 1 is outputted and "dEL" is displayed on the LCD for one second. 4. After one second elapsed, the BEEP 2 is outputted, and the EEPROM initialize mode is deactivated and the set returns to the standby state.

4. Each time a key is pressed, the segment assigned to each key turns off (see below). Also, if the [LIGHT] key is pressed, the LCD back light turns on. (It turns off at the release of LCD and ket test mode) 5. When all keys were pressed, the BEEP 2 is outputted, and the LCD and key test mode is deactivated and the set returns to the standby state.
Note 1: The pulse input is ignored during each test mode. Note 2: In the event that the VDET1 terminal (pin rl of IC101) on the key board detects "L" during each test mode, the test mode is deactivated and the set returns to the standby state. Note 3: The amplifier power turns on by the main clock operation to prepare for the BEEP output during each test mode.
