To archive an information service message use the same method as described for archiving messages. 17 9261-6366 iss 2 21/11/02 9:04 am Page 22 Secure Messaging Options FLA870 is also available as a secure messaging pager where encrypted incoming messages are decrypted, so providing security in transmission. Such messages can only be read by entering daily passwords and PINs into the receiver. Multitone have produced two secure paging products:-
1. Z-Page, which can be used for the transmission of HMG traffic to restricted level using a CESG approved algorithm. 2. KeyPage which uses the Digital Encryption Standard (DES) algorithm and is intended for commercial use. KeyPage provides effective protection from off-air message interception. Secure pagers do not support Information Services. 18 9261-6366 iss 2 21/11/02 9:04 am Page 23 Z-Page: Activation and Protection In order to decrypt and display encrypted messages your secure pager needs to be validated or loaded with its decryption key before being put into service. Unvalidated pagers can be used for normal paging only. On the Z-Pager validation is performed using a pager programming pocket (P669) connected to the PC which is to be used to send the encrypted messages. Z-Pagers require that a password is entered once each day. The password is generated by the host PC at the time of validation. To access encrypted messages an additional PIN must be entered at the time of viewing. Reading Z-Page Messages, An unread Z-Page message is indicated on the display by the symbol as for normal messages however pressing the > key will not access the Z-Page message. To read the message press the < button. If the pager is 19 9261-6366 iss 2 21/11/02 9:04 am Page 24 being used for the first time that day then the display will show two blocks of asterisks. The first block of 6 asterisks is for the message access password which must be entered daily. The second group of 4 asterisks is for the PIN entry. Use the < and > buttons to select the first digit. Then press > and the second asterisk will flash. Use the < and >
buttons to select the second digit and enter again by pressing >. Select and enter the remaining numbers in the same way. If the password and PIN have been entered correctly the pager will decrypt and display the received messages. As subsequent messages are received during the day, they can be read by entering the PIN again. Notes of Caution On the Z-Pager only three attempts are allowed at entering the correct password and PIN. If they are entered incorrectly then the receiver will immediately delete all security 20 9261-6366 iss 2 21/11/02 9:04 am Page 25 features and messages. The Z-Pager cannot then be used for secure messaging without revalidation on the host PC. If the battery is allowed to discharge fully then all security feature programming will also be deleted and the product will revert to non secure pager operation. KeyPage Operation On the KeyPager a randomly generated decryption key is already programmed during production and the key material is loaded from a diskette into the chosen message entry PC. The encryption key diskettes should be carefully stored by your KeyPage system administrator. When KeyPage encrypted messages are generated from within a networked environment, the encryption keys are stored in the network server. 21 9261-6366 iss 2 21/11/02 9:04 am Page 26 KeyPage Message Access The KeyPager has no daily password and requires only a PIN to be entered in order to read encrypted messages. An unread encrypted message is indicated on the display by the symbol. To read the message press the < button to reveal the PIN entry screen and enter the number for each asterisk in turn using the < , > and > buttons. Up to 4 attempts are allowed to enter the PIN after which the pager will reset, deleting all secure messages and further PIN entry is barred for four hours. If PIN entry is attempted the pager will display the symbol. The PIN entry lockout cannot be shortened by removing the battery. NB: Secure messages may be received in this period but may not be read. No revalidation is required on the host PC following false PIN entry nor is the secure messaging facility lost when the cell is discharged. 22 9261-6366 iss 2 21/11/02 9:04 am Page 27
. From the sub KeyPage PIN Changes KeyPage offers the additional facility of being able to enter ones own preferred PIN. To do so press > from the standby screen and use
< or > buttons to select menu select the symbol. The security control screen is displayed containing four asterisks. Enter the current PIN using the <
and > buttons and confirm each digit by pressing the > button. If the PIN is correctly entered the pager will display four zeros for an alternative new PIN. Use the < or > buttons to step each digit to the required number and confirm it by pressing >. After confirming the fourth digit the pager will display the new PIN with an arrow, Press > again and the arrow will flash to confirm acceptance of the new PIN. The pager will then revert to the standby screen. symbol and flashing
. 23 9261-6366 iss 2 21/11/02 9:04 am Page 28 KeyPage PIN Reset If the KeyPager PIN has been forgotten it is possible for the system to remotely reset the PIN to that which was first programmed in the factory. This requires that a special control code be transmitted to the KeyPager to reset the PIN. A method of verifying the user identity must be agreed with the system administrator who will supply an additional authorisation code which must be entered to restore the PIN. KeyPage Barred Access When the possible to change the PIN. If this is attempted the pager will display symbol is displayed it is not and the symbol. If the PIN has been incorrectly entered four times it will not be possible to change the PIN until the four hour lockout period has elapsed.

Clean the exterior of your pager using a clean, soft, non-abrasive cloth. If necessary, dampen cloth with water only. Avoid contact with solvents. Fault Finding If your pager appears to have a fault please check the following:
Is the pager switched on?
Is the battery dead?
Is the battery fitted correctly?
Is the +ve sign on the battery aligned with the moulded +ve sign in the battery compartment?
If you have checked the above and are still having problems please contact your Multitone dealer. 25 9261-6366 iss 2 21/11/02 9:04 am Page 30 9261-6366 iss 2 21/11/02 9:04 am Page 31 9261-6366 iss 2 21/11/02 9:04 am Page 32 Multitone Electronics plc 1999 Multitone Electronics plc Multitone House Beggarwood Lane Kempshott Hill Basingstoke Hampshire England RG23 7LL Part No. 9261-6366 Issue 2 Printed and published in England
