settings are cumulative – that is, to determine when the 7535 enters ‘Suspend’ state, the unit waits for the ‘User Idle’ state to elapse, followed by the ‘System Idle’ state and then, once the
‘Suspend’ state time has elapsed, ‘Suspend’ state is activated.
When setting the
User Idle State
,
System Idle State
and
Suspend State
, keep the following in mind. Because the 7535 ‘wakes up’ from the
User Idle
and
System Idle
states almost instantaneously following any user input (keypress, trigger press, screen tap), the timeouts you set will not slow user activity. The sum of the
User Idle
,
System Idle
and
Suspend
timeouts should be selected carefully since the 7535 will go to sleep (appear off) when this time has elapsed, saving battery power. Psion Teklogix recommends starting with a total of 10 minutes for this timeout. Setting any of these timeouts to
‘Never’ will adversely affect the battery run time.
To further reduce power consumption, carefully consider the duration of time that the display backlight is ‘on’ (see “Display Backlight” on page 77).

This dropdown menu allows you to identify whether the unit is using

User Idle State
User Idle
means that the 7535 is not receiving any user input including activities like a key touch, a scan, and so on – any user initiated activity. When the time selected in the ‘
Switch state to User Idle
’ menu elapses, the hand-held enters a
User Idle
state and begins to monitor the time specified in the
System Idle
state menu.

System Idle State
System activity includes computer activity such as serial data, an activity initiated by an application, and so on – any activity not executed by the user.
System Idle
is activated when the time specified in the ‘
Switch state to User Idle
’ and the ‘
Switch state to
System Idle
’ menu have elapsed without any activity. The 7535 begins to monitor the
Suspend
field.
Suspend State
Once the time specified in the
User Idle
and the
System Idle
fields have elapsed, the 7535 begins to count down the time specified in the ‘
Switch state to Suspend
’. When the time in the
Suspend
field elapses, the unit enters
Suspend
state.
In
Suspend
state, the 7535 CPU enters a sleep state and all peripherals are powered down to minimize power consumption. The state of the device (RAM contents) is preserved. Pressing <ENTER> or the <SCAN> button wakes the system from suspend state. When the 7535 is in suspend state, the network connection is broken.
To resume, you must re-establish the network connection.
5.3.4 Calibrating The Touchscreen
Note: Touchscreen calibration may not be enabled on your unit. If your screen appears to require recalibration, contact your supervisor.
Touchscreens rarely require recalibration. However, if your touchscreen has never been calibrated or if you find that the stylus pointer is not accurate when you tap on an item, follow the directions below.
• In the Control Panel , select the Stylus icon to display the Stylus Properties window.

Chapter 5: Configuration
Scanner Options
5.5.1 Scanner Options
Verify
The value entered for this parameter determines the number of correct additional decodes required after the initial decode before a bar code is accepted. Higher values significantly increase the time it takes to decode a bar code but also improve the reliability of the decoded bar code.
Security
This parameter controls the tolerance for decoding edge-to-edge bar codes
(Code 93, Code 128, UPC/EAN). Lower values have a lower tolerance for misreads, but they also increase the time it takes to decode the bar code. The default value of
30 is generally a good compromise setting.
Short Code
When enabled (
√
), this parameter allows scanning of short I 2 of 5 bar codes (2 characters). When disabled, these short bar codes are rejected.
Enabling “Short Code” may reduce the robustness of the decoding since the
7535 must decode more potential bar codes; it is therefore not recommended for general-purpose bar codes with 4 or more characters.
Double Click Options
Click Time
Note: This parameter only affects 7535s using scanners with aiming dot capability.
This parameter controls the maximum gap time (in milliseconds) for a double-click.
If the time between the first and second clicks of the scanner trigger is within this time, it is considered a double-click. The allowable range is 0 to 1000 . A value of zero disables this feature.
A double-click produces different results depending on whether or not a value is assigned in the “Click Data” parameter. When a value is not assigned for the “Click
Data”, double-clicking the scanner trigger overrides the target dot delay set in the
“Dot Time” parameter and initiates a normal scan sweep. If a value is assigned for the “Click Data” parameter, double-clicking the scanner trigger inserts the “Click
Data” value rather than initiating a scan.

Scanner Options
Click Data
For both integrated and external scanners, this parameter determines which character is sent to the application installed in your 7535 following a double-click.
Enter the ASCII value of the character desired from 0 to 255 . You can also press the
<LEFT> or <RIGHT> arrow keys to scroll through a set of ASCII characters not available from the keyboard.
Display Options
Indicator
When this parameter is enabled (
√
), the laser warning logo appears on the display whenever the scanner is activated.
Result
When this parameter is enabled (
√
), the type of bar code and the result of the scan appear on the screen. Note that this information is only displayed after a successful decode and is visible only while the scanner trigger is pressed. When the trigger is released, this information is cleared from the screen.
Dot Time
The value selected for “Dot Time” determines how long the targeting dot remains on before the scanner switches to a normal scan sweep. The allowable values are:
0, 0.1, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 seconds. A value of 0 (zero) disables the target dot.
Result Time
The value assigned to the “Result Time” parameter determines how long the scan results of a successful scan are displayed on the screen. Time is measured in seconds, and a value of “0” (zero) disables the parameter.
Note: To remove the scan result from the screen before the “Result Time” has expired, perform an unsuccessful scan.

Include Chk
If this parameter is enabled (
√
), the check digit is included with the decoded bar code data.
AIAG Strip
If this parameter is enabled (
√
), the AIAG data identifier is removed from each decoded Code 39 label. The data identifier occurs in the first position next to the
Code 39 start character. It can be a single alphabetic character or a series of numeric digits followed by an alphabetic character. This identifier defines the general category or specific use of the data contained in the rest of the bar code.

Code 39 Settings
Note: If your unit is operating with the Psion Teklogix TESS application, this parameter should not be used in conjunction with the TESS AIAG feature.
This is because the 7535 hand-held performs the strip function before it processes the data through the AIAG feature; if the prefix is stripped, the data is not identified as AIAG.
Err Accept
If the “Err Accept” and “AIAG Strip” parameters are enabled (
√
), all label data without an AIAG identifier character is accepted. If the “Err Accept” parameter is disabled and the “AIAG Strip” parameter is enabled (
√
), the label data is not accepted.

Field Size
The field size is the length of the field after the first character is stripped and the prefix and suffix characters are added. If the field size is non-zero, only bar codes of that length are passed through.
Prefix Char
This character, if non-zero, is added before a successfully decoded bar code.
Enter the ASCII decimal equivalent of this character. Enter a value of 0 (zero) if no prefix is to be added.
Suffix Char
This character, if non-zero, is added after a successfully decoded bar code.
Enter the ASCII decimal equivalent of this character. Enter a value of 0 (zero) if no suffix is to be added.
Strip Leading
This parameter determines the number of characters that will be removed from the beginning of the bar code before the prefix character is added.
Notes: 1.
The appended character is treated as any other keyboard character.
For example, if <BKSP> is pressed, the usual action for that key is performed. If your unit is operating with the Psion Teklogix ANSI emulation application, the 7535 transmits the escape sequence associated with the function immediately after the bar code data.
2. For Code 39 bar codes, the “AIAG Strip” is performed before the
“Strip Leading”.
Strip Trailing
The value entered in this parameter determines the number of characters that will be removed from the end of the bar code before the suffix character is added.

An addendum is a separate bar code, supplementary to the main bar code.
This parameter provides three options: Disabled, Optional and Required .
Depending on the value chosen for this parameter, an addendum is recognized or ignored.
When “Addendum” is set to Disabled, the scanner does not recognize an addendum. If this parameter is set to Optional, the scanner searches for an addendum and if one exists, appends it to the main bar code. When the parameter is set to Required, the scanner does not accept the main bar code without an addendum.
