Battery Replacement Procedure
Replacement batteries are available from Hakko Electronics.
1. Replace the battery “V7-BT” within three minutes after the V7 unit is turned off. If it is
not possible to replace within three minutes, use the V-SFT editor (cable: V6-CP) or a
CF card and make a backup copy of data in the SRAM cassette.
• When using the V-SFT editor:
1) Start the V-SFT editor.
2) Click the [Transfer] icon. The [Transfer] dialog is displayed.
3) Select [Display] for [Transfer Device], and [SRAM Data] for [Transfer Data]. To
save a backup copy from the V-SFT editor on the server via Ethernet, check
[Transfer through Ethernet/IP Address of the V7 Equipped with SRAM]. Keep
[Use Simulator] and [Read Comments in Data Transfer] unchecked.
4) Click the [PC ←] under [Transfer Mode].
5) Save the read data in the “*.RAM” file.
• When using a CF card:
For the backup procedure with a CF card, refer to “Chapter 2 MONITOUCH
Operations.”
2. Turn the unit off, and open the battery holder. A battery is set at the socket.
3. Unplug the battery connector, and remove the battery
from the socket. When removing the battery, push the
center of the battery holder cover as shown on the right.
4. Set a new battery. Hold the battery with its red cable side
(marked with SANYO) facing towards the printed circuit
board and the cable hanging down, and insert the battery
into the socket. Insert the battery in the “a” side first, and
push it down to “a” while inserted in the “b” side.
5. Plug the battery connector and close the battery holder
cover.
6. Remove the existing caution sticker. Enter a date five years from now for “Battery
Replacement” on the new caution sticker, and attach it to the backside of the V7 unit.
7. When a RAM file is saved in step 1, turn the V7 unit on and load the RAM file to the unit.
