User manual C-SCOPE CS7

[. . . ] In the event that your detector should ever require to be serviced, this package will be most suitable for postal protection. They are designed with lasting quality, high technology, and above all, value for money. The only way to realise this value is to carefully study and understand this instruction manual. You will then be able to obtain all the advantages designed into your detector. [. . . ] This can be easily seen by observing the black `O' ring through the clear cover. Note: batteries should not be left in the detector for long periods where they could leak, so remember to remove them if the detector is not going to be used for several weeks. TAKE CARE Damage to the sealing surfaces can lead to extensive internal deterioration which can not be covered by our warranty. BATTERY CHECK A battery condition indicator is provided on the detector. To do this for the first time prior to reading the remainder of the operating instructions proceed as follows:A) Turn the FREQUENCY control to BATT. CHECK and turn the THRESHOLD control clockwise until it `clicks' away from the OFF position. The GREEN LED will come ON if the batteries are good; the YELLOW LED will come ON indicating the batteries are in poor condition. If the RED LED 7 comes on the batteries should be replaced, or recharged in the case of rechargeable batteries. B) Turn the THRESHOLD control to OFF. Checking The Batteries Red Green Yellow CONTROLS AND WHAT THEY DO The control panel comprises two rotary controls, signal and battery condition indicators. ON/OFF - THRESHOLD control is used to set the audio tone of the machine. This is normally set so that the tone is silent or just on the point where the tone is starting to break through. There is no performance advantage in having a loud tone constantly present. CHECK ­ FREQUENCY TARGET INDICATOR BATTERY CONDITION INDICATOR 8 9 ii. BATTERY CHECK - FREQUENCY control has two main functions in addition to the battery test which is at the switched, fully anti-clockwise position. Small changes to the frequency setting can be used to minimise interference from other signal sources. Changing the frequency also affects the machine's sensitivity to aluminium alloy based rubbish such as silver paper and pull tabs. By rotating the control clockwise, the machine's sensitivity to such objects will be progressively increased. When used in the surf or under water it may be necessary to reduce the frequency setting. Turn the control anti-clockwise to minimise threshold variations caused by changing depths of sea water. The audio frequency is also varied with this control giving audible indication of the frequency setting ­ this is useful when using the machine whilst under water. If the frequency control is rotated fully anti-clockwise the battery check position is reached. Whilst in this position the battery indicator will show the condition of the batteries. If the GREEN indicator fails to come ON then the batteries should be changed. The CS7 is a low current drain design and typical battery life will be 25 hours of intermittent use. iii. TARGET INDICATOR This group of four bright RED LEDs will illuminate whenever the audio tone goes above a preset level ­ indicating that a target has been located. iv. BATTERY CONDITION INDICATOR Three LEDs indicate the battery voltage ­ Ø GREEN ­ good batteries Ø YELLOW ­ used batteries, some life left Ø RED ­ exhausted batteries v. VOLUME (INTERNAL ADJUSTMENT) The volume of the detector is factory set for optimum performance without causing discomfort. [. . . ] Ensure that they are tight and the batteries are securely clipped into place. (b) Interference from a vehicle using a radio transmitter or possibly a stationary source of electromagnetic radiation - if this occurs then change the FREQUENCY setting. If the problem persists then the best remedy is to wait until the transmission stops. Intermittent Sound From Headphones (a) This could be due to poor battery connections. [. . . ]
