Setting/Starting the Watch Timer

The Watch Timer is a pre-settable countdown timer that activates the alarm when it reaches “0”. It then counts UP. The Watch Timer can be preset anywhere from (1) second to (99 minutes 59 seconds). This selected value is saved to memory and the timer is automati-cally preset to this value each time the key is pressed. The Watch Timer quietly “clicks” down the last (10) seconds to warn you that the alarm is about to go OFF.

To preset the Watch Timer press and hold the key for (10) seconds while viewing the Time-of-Day. Press the key to switch between minutes and seconds. Press the key for 1/2 second to save the value. To view/preset/start the Watch Timer press the key. To view the current status of the Watch Timer without presetting it, press the and keys.

Introduction

The CT60-A Clock, Watch/Race Timer is an accurate 12/24 hour format clock with a re-settable down counting watch or race timer and eight time-of-day alarms.

The Watch/Race Timer can be preset to a value from (1) second to (99) minutes and counts UP after reaching “0”. The CT60-A will quietly “tick” or “beep” away the last (10) seconds to warn you the alarm is about to go o�.

(5) levels of backlighting can be selected. All setup, calibration constants and alarm values are saved to a non-volatile memory.

Installation

All of the Aircraft Digital Instruments are of the standard aircraft 2.25” diameter and mounting hole layout dimensions. They can be mounted in your panel either from the front as a surface mount installation, or in the conventional manner from behind. When placing and mounting on the backside of you panel you will not need any additional hardware such as lock nuts, tinnerman clips, bug nuts or the like. The mounting holes in the Bezel are speci�cally sized so as to grip the included #6-32 allen socket screws just like a elastic nylon stop nut would. The 6-32 screw is merely aligned squarely with the hole and with gentle pressure applied to the allen wrench, screwed in. Should you prefer to surface mount the gauge, the Bezel’s screw holes can be easily drilled out to a clearance hole diameter, allowing then for either a drilled and tapped 6-32 threaded hole on your panel, or passing through your panel to be secured with standard hardware.
