NOTE 1: If you’re using a phone or headset without a menu screen (such as a
WH-10 or C.H.I.P), the steps for placing calls are basically the same
as for a phone with a menu screen. However, most WH-10 phones do
not have a “+” key or an “End Call” key. Therefore, anytime you are
instructed to press the “+” key, you should substitute this action by
pressing the hook switch down quickly (less than a second). If you
press the hook switch down for more than a second, it will serve the
same function as pressing the “End Call” key.
NOTE 2:“Air-Ground” MUST be displayed on the “Services” menu in order to
place and receive calls. The “Services” menu is displayed when the hand
set is “On-hook.”
NOTE 3: You may manually place the handset “on-hook” or “off-hook” by press-
ing “+.”
NOTE 4: If while setting up a call, the “OCXO Cal, Needed” message is displayed,
this indicates that the ARTU requires factory calibration.
