CSR1 8 VELLEMAN
BRIGHTNESS: This option sets the brightness level of the backlight. In normal daylight the backlight is not required
and it should be set to 0. At night or in conditions of poor light the backlight level should be adjusted by rotating the
MENU/SCROLL control and then pressing the ENTER button when satisfied, this will store the setting.
IMPORTANT NOTE: The backlight consumes a lot of power compared with the low consumption circuitry of the rest
of the CSR1. For this reason to ensure long battery life the backlight should only be used where necessary and the
brightness level kept to a minimum. When the backlight is on the
symbol appears on the display to prevent
inadvertent use.

The default setting of 50 is a good general setting and should be adequate for most sites. However, a fine adjustment
is provided to allow the operator to adjust the CSR1 to give optimum performance on a particular site. The level is
adjusted by rotating the MENU/SCROLL control. An incorrect setting will result in a fluctuating signal on the RADAR
display and frequent ‘0’ targets on the ID display. To find the optimum ground setting, raise and lower the head
above an area of ground free from any targets then adjust the ground setting for minimum audio fluctuation and ID
indications. An alternative method is to set the Pin Point gain to 8 and then lower the head to an area of ground free
from any targets. If the audio level increases then decrease the ground setting, if it decreases, (goes quiet), then
increase the ground setting.
NOTE: If BEACH is selected then an incorrect ground setting will result in frequent ID targets in the range 3 to 6
depending on beach conditions. Adjust the ground setting as described above.

This can be used to change the operating frequency of the CSR1. Three frequencies are provided. Generally the
middle frequency should be used but the others can be used if interference from other metal detectors is
experienced. Use the MENU/SCROLL control to highlight the desired frequency and the press the ENTER key to
store the setting. NOTE: the frequency does not change until the ENTER key is pressed.

This option allows the selection of either rechargeable batteries or alkaline batteries. It is used to ensure that the
battery monitor accurately shows the state of charge of the batteries. Use the MENU/SCROLL control to highlight the
desired battery type and then press the ENTER key to store the setting.
7. General Hints
a. Pinpointing
Move the search head to one side of the target. Press and hold the Pin Point button. Sweep the search head over
the target slowly whilst monitoring the RADAR display. The target is directly below the centre of the search head
when the signal is largest. If the RADAR signal is too broad then either move the head closer to the target and
release and press the Pin Point button, or simply raise the search head slightly off of the ground whilst sweeping the
head over the target. Make a mental note of the position of the maximum signal then turn through 90 degrees and
repeat the above procedure. Again make a mental note of the position of maximum signal. The point at which both
signals peak, is the position of the target. Dig carefully to avoid damaging your find.
