AC Adaptor

Note:

There are two types of AC adaptors: one for 100 V and one for

200 V. Confirm that the AC adaptor you use matches the

power supply voltage of the power outlet.

To install the AC adaptor:

Confirm that the power is turned off at the GX-1 main unit:

that is, the switch is toggled down to

Insert the AC adaptor into the power supply slot on the

right side of the GX-1.

Plug the power cable into the AC adaptor.

Plug the power cable into the power outlet.

Note: Backup by DC power

If +11 to 16 V DC power is supplied to the DC IN connector

while using the GX-1 with an AC power supply, the DC power

supply backs up in case of a failure of the AC power.

However, if the supplied voltage is +16 V DC or greater, the

DC power supply takes priority.

Note: Removing the AC adaptor

To remove the AC adaptor, push the eject lever beneath the

power supply slot. The AC adaptor pops out with the force of a

built-in spring—be careful.

WARNING

Before installing or removing the AC adaptor, discon-

nect the power cable from the adaptor. If the cable is

left connected to the adaptor and a power outlet, the

power supply voltage is applied to the output termi-

nals of the adaptor and might cause an electric

shock.

Preparing the Power Supply

■

DC Power Supply

The GX-1 can be operated on +11 to 30 V DC.

To connect the DC power supply:

Confirm that the power is turned off at the GX-1 main unit:

that is, the switch is toggled down to

Plug the DC power cable into the DC IN connector at the

rear of the GX-1.

Note: What happens when the DC supply voltage drops
to +11 V or less?

The message LOW BATTERY appears on the status bar of the
provided software's window. When you see this message,
promptly quit recording. If data is being recorded to the GX-
1's memory at this time, transfer the data from memory to a
removable medium or PC. When the power supply voltage fur-
ther drops to +10 V or less, the GX-1 automatically shuts
down.

Note: Backup by battery pack

If the battery pack is installed in the power supply slot while
using the GX-1 with a DC power supply, the DC power supply
and battery pack are used in parallel. This way of use is recom-
mended when the DC power supply is unstable. Also in this
case, if the supply voltage drops to +10 V or less, the GX-1
automatically shuts down. However, since an idling current
flows even during shutdown, turn off the power switch to pre-
vent excessive discharge of the battery pack.

Battery Pack

To install the battery pack:

Confirm that the power is turned off at the GX-1 main unit:
that is, the switch is toggled down to

Insert the battery pack into the power supply slot on the
right side of the GX-1.

Notes:

• What happens when the battery voltage drops to +11 V

or less?

The message LOW BATTERY appears on the status bar of
the provided software's window. When you see this mes-
sage, promptly quit recording. If data is being recorded to
the GX-1's memory at this time, transfer the data from mem-
ory to a removable medium or PC. When the voltage further
drops to 10 V or less, the GX-1 automatically shuts down.
However, since an idling current flows even during shut-
down, turn off the power switch to prevent excessive dis-
charge of the battery pack.

• Removing the battery pack

In the same way used to remove the AC adaptor, push the
eject lever.

• With a fully charged battery pack, the GX-1 can record con-

tinuously for approximately 40 minutes (when using an AIT
or an MO).

• To recharge a battery pack, follow the documentation for the

battery charger.

• Nickel metal hydride batteries are susceptible to a "memory

effect". Discharge the battery fully before recharging.
