Scope
This manual is designed to assist in configuring the TSUR-400 and to guide the user through the
programming features. The TSUR-400 displays various screens, which enable the user to easily learn
and operate the unit.
General Functional Guidelines
Before commencing operation, make sure the battery is charged and properly attached. Using the
battery charger provided, the battery can be charged individually by inserting the spacer, or it can be
charged while attached to the TSUR-400. Make sure the antenna is properly attached.
Four keys labeled FN (P0), DN (P1), UP (P2), and PWR (P3) are used to control and set all functions.
Each key is variable dependant upon the current screen displayed on the TSUR-400. Please refer to
Appendix C, TSUR-400 Menu Flow Chart at the back of this manual.
FN (P0) Key
The FN key operates as a Function Key and is used to access the various menus, advance or accept
setup parameters, and toggle menu items On or Off. The FN key is also used to exit from the Message
screen or to enter the Menu system.
DN (P1) Key
The DN key is a scroll down key used for scroll down menu options. The DN key also decreases a
value or field when in a Level 1 or 2 menu option. Pressing the DN key when in the Main screen will
take the user to the Message screen.
UP (P2) Key
Depressing the UP key will scroll upwards in a menu, or increase a value or field when in a Level 1 or
2 menu option. When in the Main screen, pressing the UP key will display the Splash screen for 3
seconds. Pressing the Up key in the Message screen will display the Main screen.
PWR (P3) Key
The PWR key turns the unit’s power or display backlight ON or OFF. Depressing the key for 3
seconds when the TSUR-400 is Off will turn the unit ON. Depressing and holding the key again for 3
seconds minimum will turn the TSUR-400 OFF. When the unit is ON, sitting at the main message
screen waiting for a message, briefly depressing the key will enable the display’s backlight for the
configured time period. Momentarily depressing the PWR key again before the backlight time-out will
deactivate the backlight. Depressing any other key when the backlight is ON will restart the backlight
time-out period. When the user is in either Menu Level 1 or Menu Level 2 screens the P3 key may be
used as a quick escape key to return to the main screen.
