Make sure the AC source voltage is set at the rating

±10%, 50/60Hz. For power up sequence, see page17.

Otherwise the internal fuse might be blown out. For fuse

replacement procedure, see page35.

TTL does not activate (pressed Shift + Wave key)

You need to turn On the output first. Press the Output

key, then press Shift+Wave. For details, see page25.

How can I get out of TTL/−40dB mode?

For TTL: press the Shift key, then the wave key. For

details, see page25.

For −40dB mode, press the Shift key, then 3. For details,

The device accuracy does not match the specification.

Make sure the device is powered On for at least 30
minutes, within +18°C~+28°C. This is necessary to

stabilize the unit to match the specification.

What are these error messages?

Several messages appear when trying to set the frequency

in irregular ways. Page37 summarizes the messages.
