- Page 29 SECTION 5—PERFORMANCE ADJUSTMENTS MENU ITEM DESCRIPTION AXES Axes Selection redirects the driver input command to another axis. For example: The for- SELECTION ward movement of the joystick can be changed to a reverse command. Each of the four input axes can be redirected to any output axis. Also, OFF can be selected which will disable any response from that axis.
- Page 30 SECTION 5—PERFORMANCE ADJUSTMENTS MENU ITEM DESCRIPTION TILT/RECLINE This function appears when the MK5 Tilt Recline Control Module (TRECM, TRCM or TAC) is installed. There are six (6) operating modes in the TILT/RECLINE function. 1. 4-SW Four Switch mode uses all four quadrants of the joystick. Each command is momentary (a command is active only as long as the joystick is displaced in that direc- tion).
- Page 31 SECTION 5—PERFORMANCE ADJUSTMENTS MENU ITEM DESCRIPTION TILT/RECLINE With this program selection the user does not have to use the emergency stop/reset switch WITH STANDBY to select the TILT/RECLINE function. First the user waits for Standby time-out. (Set by the SELECT TIME function.).
