MODE Keys

Alternate presses of a MODE key will turn the mode

(TRIG, GATE, AM, etc.) on or off, and when the function is on the associated lamp is lit.

If you press the EDIT key then press a MODE key you will see the edit menu for that mode. The associated lamp flashes when the edit menu is displayed.

Some of the modes share keys with the numeric keypad. For example, to see the edit screens for HOP mode, press EDIT then the numeric 5 key.

To return to the main menu from any edit menu, press the ESCAPE key.

UTILITIES Keys
The UTILITIES keys give
access to the STORE,
RECALL and REMOTE
edit menus. The instrument
can store up to nine set-ups
(numbered 1 to 9), and can
recall any of those plus
set-up 0 which is the factory
default set-up and is not
editable.	shx0011f.gif

The MAN/SYNC key is used for manual triggering and synchronizing two or more generators when suitably connected together. Further information on synchronizing two generators is given in the Users Manual.

OUTPUT Key

The OUTPUT key turns the MAIN OUT on and off. When the output is on the LED next to the key is lit.

The default state at power-shx0018f.gif up is with the output off.
