[. . . ] Remove the batteries if this device is not going to be used for a long period. Do not charge non rechargeable batteries like Alkaline batteries in the charger. 6 Twintalker 9500 13 Using the Twintalker 9500 The display illustrations in next pages only show the icons or display informations of the functions that are explained in the text. Hold the unit in a vertical position with the microphone 10cm from the mouth and speak into the microphone. 1 Switching On/Off the PMR radio • Turn the “On-Off/Volume Knob” 1 clockwise. To check the channel activity use the monitor function ( See chapter “13. 6 Changing Channels • • • Press the -button 7 once, the current channel number flashes on the display. 2 Battery Charge Level/Low Battery Indication The battery charge level is indicated by the number of squares present inside the battery icon on the LCD Screen. Battery Full Battery 2/3 charged Battery 1/3 charged Battery empty When the battery charge level is low, the battery icon will flash and a beep will be heard to indicate that the batteries need to be replaced or recharged. 3 • • Adjusting Speaker Volume Turn the “On-Off/Volume Knob” 1 clockwise to increase the speaker volume. 7 If no button is pressed within 5 seconds during setting, the unit will return to standby. CTCSS (Continious Tone Coded Squelch System) / DCS (Digital Coded Squelch) License free PMR radio's operating on the 446 MHz frequency band, like the Twintalker 9500 PMR, have 8 available radio channels. If there are many PMR users in your neighborhood, there is a chance that some of these users are operating on the same radio channel. To prevent that you receive signals from other users, sub-channels have been integrated. Two PMR radio's will only be able to communicate with each other when they are operating on the same radio channel and when they have selected exactly the same sub-channel. There are two kind of sub-channels : • Continuous Tone Coded Squelch System (CTCSS) • Digital Coded Squelch (DCS) When using CTCSS, a low frequency tone (between 67 and 250 Hz) will be transmitted along with the voice signal. Due to filtering, these tones will generally not be audible so they will not disturb the communication. DCS is similar to CTCSS, but instead of sending a continuous tone of a selected frequency, a digital data transmission is added to the radio signal. This Digital Code is transmitted at a really low rate, around 134 bits per second (the code is 23 bits long). Since earlier models will only support CTCSS it will be better to use DCS to prevent that other users will be audible during your PMR conversations. 4 Receiving a Signal The unit is continuously in the receive mode when the unit is switched ON and not transmitting. In order for other people to receive your transmission, they must also be on the same channel and have set the same CTCSS code or DCS code. [. . . ] Consumables or defects causing a negligible effect on operation or value of the equipment are not covered. The warranty has to be proven by presentation of the original or copy of the purchase receipt, on which the date of purchase and the unit-model are indicated. 2 Warranty handling A faulty unit needs to be returned to an authorized service centre including a valid purchase note and a filled in service card. If the unit develops a fault during the warranty period, the service centre will repair any defects caused by material or manufacturing faults free of charge, by either repairing or exchanging the faulty units or parts of the faulty units.
