Calibrating The Touchscreen

Psion Teklogix 7535 G2 Hand-Held Computer User Manual 19

2.5 Calibrating The Touchscreen

If you have the 7535 G2 touchscreen feature, it is factory-calibrated and ready-to-go; how-

ever, over time the touchscreen's operating parameters may change, and it may need to be

recalibrated for correct operation. Refer to “Calibrating The Touchscreen” on page 51

for details.

2.6 Configuring Your Radio

Psion Teklogix provides two types of 802.11 Compact Flash (CF) wireless LAN radio cards

for the 7535 G2: the Motorola RA2043a/b/g radio and the Summit RA2041b/g radio. Both

models are Direct Sequence Spread Spectrum radios.

If your 7535 G2 is equipped with an RA2041 CF radio, follow the steps under “Summit

Client Utility (SCU) For RA2041 802.11b/g Radio” on page 28 to set up this type of radio

for communication with a wireless LAN.

If your computer is equipped with an RA2043 CF radio, follow the steps outlined under the

heading “Configuring An IEEE 802.11 Radio In The Unit”, below.

2.7 Configuring An IEEE 802.11 Radio In The Unit

The most common 802.11 settings are configured as defaults. However, there are some

fields that must be completed, including the SSID of your access point and the security

methods implemented in the network (including access keys).

Note: Keep in mind that 7535 G2 Hand-Held Computers can be ordered with or without

touchscreens, and that the touchscreen function can be turned off (see “Touch” on

page 125).

Note: In most situations the configuration of your 802.11 radio will require parameters,

settings, and access keys from a network administrator.

Network administrators should review the detailed security information in this sec-

tion in order to effectively configure the 802.11 wireless network.

Important: If the 7535 G2 is equipped with a radio that has never been configured, the

radio settings dialog box opens automatically when the unit is powered on.

In this case, skip to Step 4 on page 21.
