7.10. Void and Correction
This chapter informs you about the void function. Whether
or not you can use this function depends on programming
and configuration of your MobileTouch POS system.
You can cancel bookings if for instance an operator made
false entries. Furthermore, you can program and configure
the MobileTouch so that PLUs are cancelled and the re-
spective invoice is corrected, if a customer returns items.
7.11. Using a wireless network for data transfer
This chapter tells you how to use the wireless network for
data transfer.
Prerequisite for using a wireless network is that it was
installed as described in chapter 6.3 “Installing a wireless
network” on page 64.
Functions like e.g. calling a GC only work if radio commu-
nication between MobileTouch POS system and an access
point is established. This depends on the programming of
your MobileTouch POS system, e.g. when guest checks are
stored on a GC server.
If radio communication between MobileTouch POS sys-
tem and an access point is interrupted, it is automatically
restored as soon as the radio signal is available again.
Data stored on the MobileTouch POS system is transferred
afterwards.
