The menus on the handset show or hide certain options depending upon how the handset was intended to be delivered. It might deliver as part of a C610A IP system, in which case the menu option to “Select Services” is shown. The handset may be configured to deliver as part of a Gigaset C610A-L410 combination
This difference only comes into play when you’re adding an additional C610H handset to an existing C160A IP system. The initial shipment of C610H expansion handsets to North America were preset in manufacturing as if they were for use in a non-IP capable installation. This bothered some people who wanted matching feature sets on all of their handsets.
While it took some time to get Gigaset to respond to this concern, they eventually published a keystroke sequence that will enable those menu items that are by default hidden on the C610H accessory handsets. Here’s how it’s done:
“ok everyone, I have the procedure for re-instating the "Select Services" icon in the menu. This will work for the C610H add-on handsets you have where you notice that the menu looks different than the menu on the handset that came with the C610AIP system.
Get into the menu (right click silver 4-way navkey)
Type in *#7337#
Enter in the 15 digit string 52795 52281 52473
Press “ok” softkey on bottom right of screen.”
Subsequent shipments of the C610H to North America may arrive preset for use with the C610A IP system, in which case this procedure is not required.
In recent months there have been a few threads involving Gigaset in that same forum. This has prompted to Gigaset to consider launching some further way to post such information to the web. Further details are as yet unreleased, but it’s good to know that they are listening.
