-The volume can be adjusted with the use of a small screwdriver, both flat and cross head screwdrivers may be used. On the back of the Bridgetimer a total of 4 holes can be found, the two uppermost may be used to mount the Bridgetimer, the outermost is used for restoring the default settings and the innermost is used for adjusting the volume.

On the back of the Bridgetimer a total of 4 holes can be found, the two uppermost are used to mount the Bridgetimer on a wall, the outermost is used for field upgrades of the firmware. The innermost (closest to the speaker) is used for adjusting the volume.
 As the circuit board and the potentiometer are positioned relatively deep within the timer, some effort may be required to locate the potentiometer. In order to prevent short-circuiting it is advised to search for the potentiometer only when the the timer is unpowered.

-When turned on the clock always starts back at P1. The reason is that when for example there are two weekly events that require different settings, starting back up on the old settings guarantees that you will always start with the wrong settings active. Starting back at P1 all the time means we stand a chance of getting it right some of the time....

-If the program that your club uses is always the same, just adjust the default P1 program. You do this once and then adjust the change time before the first round or the first round itself on each event.

-If you share the clock between two events that have different timings, I recommend programming the schedules for those events into P2 and P3. People who are not familiar with the clock will quickly adjust P1 to whatever event is then being played. If you know what you're doing you can even quicker just select the proper program. In my experience P1 gets messed up "by the other club" all the time.

-To adjust the brightness of the numbers, turn off the clock, press and hold the '''pause''' button, and turn the clock on. The display should now show an "I" (from Intensity) as well as the current value. You may adjust (using the '''up''' and '''down''' buttons) from 0 to 99. The default of 33 seems good for normal use. During daytime or outside even brighter might be useful. Each '''up''' or '''down''' keypress adjusts the intensity value by 3 units. The lowest intensities will flicker the display. Don't use those.
