From: marttanenSubject: Extra functions for Standard C528/520 Sender: usenetOrganization: Nokia Data Communications Date: Fri, 21 Aug 1992 21:45:42 GMT EXTRA FUNCTIONS FOR THE STANDARD C520 AND C528 ADDITIONAL FUNCTIONS WHILST IN SET MODE WHILE HOLDING THE FUNC BUTTON Press the 0/SET SB button to enter set mode See Section 15 in manual. Whilst still in set mode the following btttons can be pressed, together with the FUNC button, to provide the these functions buttpn fuction. [3/PO] Changes band in use in extended coverage mode UHF Only i.e 300 MHz / 400 MHz / 800 MHz / 900 MHz [4/FL DM] Displays a "." between 2nd & 3rd Digit. What else it does is a mystery, if anyone knows please let me know. 6. Toggles the tunning steps on the knob on top whilst FUNC is depressed, between 1 MHz and 0.1 MHz. 8/RPT Enables / Disables Cross band talk through mode..When Enabled a "." appears to the top right of the memory number position 9/REV Toggles UP and DOWN buttons between the normal steps and 10 MHz steps DWN/* PS Enter cloning mode Transfers all memory data between 2 x C520/528`s Tune both radios to the same frequency on one of the bands Enter cloning mode on both radios Press PTT on hhe radio that contains the memory data, A series of DTMF tone will be heard for approx 2 minutes The receiving radio`s memories will now be identical to the transmitting radio 2. EXTRA MEMORY FUNCTIONS, 40 MEMORY CHANNELS or SEPARATE TX/RX FREQ`S Although the standard manual states that 20 memories are available split between VHF and UHF bands, in fact there are 2 memory channels for each memory number on the VHF and UHF bands These can be used in 2 ways One way is to double the number of simplex channels availible, another is to provide programable RX and TX frequencies for each memory number a PROGRAMMING SEPARATE RX & TX FREQUENCIES IN ONE MEMORY LOCATION 1 In VFO mode select your RX frequency. 2. Press FUNC and V/M ENT buttons together. 3. Press the memory number to be programmed. 4. Press V/M ENT button to return to VFO mode. 5. Select your TX frequency. 6. Press V/M ENT and FUNC buttons together. 7. Press FUNC button together with the memory number to program "+-". Will appear in the repeater shift display to indicate that the memory channel is now in split frequency mode. Once a memory location has been put into split frequency mode it cannot be changed back to a simplex memory unless it is programmed as an extra channel see below or a reset is carried out. Pressing FUNC and 9/REV will cause the RX and TX frequencies to be swapped b. PROGRAMMING EXTRA MEMORY CHANNELS, EXTENDS TO 40 MEMORIES Program the first 10 memories on each band as per the manual To program the additional 10 memories on each band follow the instructions below. 1 In VFO mode select the frequency required. 2 Press FUNC and V/M ENT buttons together. 3 Press FUNC and A/CL Buttons together an M will be displayed. 4 Press the memory number to be programmed to recall these extra memories. Either use the rotary tunning control in memory mode, which will now cycle through all programmed memories. Or enter memory mode and press [FUNC] and [A/CL] together and the bar will appear above "M" indicator as when it was programmed, pressing buttons 0 to 9 will then recall the extended channels. The extended memory channels can have repeater shifts and CTCSS tones programmed in to them in the normal way BUT the value of the repeater ofset and the frequency of the CTCSS tone will be the same for both of the channels stored in one memory location i.e memory 1 and -1 will both have the same repeater ofset but if the ofset is not activated on channel -1 then it can be used as a simplex channel All the functions for the standard C528 are as below If anyone out there has any that aren't listed, please mail to me. Standard C520/C528 Modifications. This file is a compendium from to others being bandied about the place. It is hoped this will be the better of them, being the easiest to follow. o. To open up the rx only up on the unit on VHF:VHF F+0 F+D o To add 320-400 MHz, 400-480 MHz, 820 - 900 MHz, 900 - 980 MHz: UHF F+L F+0 F+B F+L F+3 A o To Expand Tx/Rx coverage, do both the above in that order, then: VHF F+6 change step to 12.5 MHz A F+8 F+8 F+C Tune down to 144.9875 F+0 F+D PTT F+8 F+C o. To Store independent transmit/receive frequency in one channel:Enter receive frequency into dial F+D Enter transmit frequency into dial F+D F+A F+ A o To Clear the tx assignment offset: F+D F+A ++A F+A A. To Clone one set to another: B B F+0 F+PS then key up on the set to clone from. Set mode key assignments: The set mode allows a number of user parameters to be customised according to individual taste. Set mode is initiated by pressing F+0. The following are entered after going into set mode:0 Turns off the beep tones on each keypress F+0 Sets band edge limits, i.e 0079=100-179, 400-479 3060=130-160 1 Changes count of paging operations tone, one beep or 5 F+1 set tx delay on carrier drop when using as cross-band repeater. 2 Enables entry of the 1 kHz figure on direct keypad entry F+2. Stop scan on busy channel even if CTCSS doesn't match. 3 Sets mod delay on paging Tx to either 450 ms or 750 ms F+3 Switch UHF bands between 300/400/800/900. 4 Mutes short noises during squelch operation F+4 Keypad entry of 4 digit or 3 digit frequency. 5 Turns on and off the auto power off function F+5 Pager Audio Mute Mutes any audio that follows the paging signal. 6 Enable/Disable the rotary channel knob when keypad locked F+6 Fast tune F+KNOB gives either 1 MHz steps, or 100 kHz. 7 Sets the CTCSS tone frequency F+7 either dual tone multi frequency, or single Tone Frequency. 8 Sets the offset repeater frequency F+8 Cross Band Repeater Enable/Disable (Identified on display by a ".") 9 Changes the LAMP button into the REV button F+9 Up and Down keys either act as the knob, or as 10 MHz steps.
