Thank you for choosing the Safetalk, a state-of-art encryption phone. Safetalk is a
high-class digital communication security telephone designed to operate under triple DES,
a widely recognized international encryption standard to prevent eavesdropping. To
ensure the best performance, please read the following instructions carefully before
installing and operating the telephone.
NOTE: PLEASE INSTALL “SAFETALK” DIRECTLY TO THE TELEPHONE LINE
FROM THE CENTRAL OFFICE (PSTN). DO NOT INSTALL “SAFETALK” BEHIND
ANY OTHER DEVICES.

※NOTE:
1. This unit utilizes Triple DES, an advanced encryption algorithm. Under
“SECURE Mode”, the voice data is compressed and encrypted. Therefore, the
user may notice that voice quality is slightly different than when under normal
“Clear Mode” calling.
2. Once SECURE mode has been invoked, the unit can not return back to CLEAR
mode during the same call. This operation is designed to insure that the user
cannot unintentionally interrupt the secure communications channel once it has
been established at both ends. Furthermore, during SECURE mode conversation,
if there is any extension line eavesdroppers or wiretaps activated during the call,
SafeTalk has special protective circuits to detect and interrupt the conversation
in order to ensure the ultimate in voice security.
3. In certain countries, the fixed line operators may route the calls by various
networks (such as VoIP networks) for long distance and/or international calling.
This may affect the key exchange process; which is enabled by SafeTalk’s
built-in algorithms. In these cases, the user may need to press the “SECURE”
button MORE THAN ONE TIME to establish SECURE connection.

Page: 8/
12
Page 9
and all keys will not function. You can set up the system to unlock automatically
whenever there is an incoming call. <ON> will enable the auto unlock function. If

The default setting is <1>.
7. AUTO SECURE：After you press “SECURE”, the built-in RSA algorithm will generate
keys to establish the secure link. You can choose either to let the system generate the
secure keys automatically or to manually enter random numbers as secure keys. <ON>
means that the system will generate keys automatically. (The key will be different each
time.) <OFF> means that you have to key in random numbers (within 8 digits) to initiate
the secure link. The default setting is <On>.
VI. Basic Operation:
Make a phone call: (1) When the system is not locked, (LCD shows “READY”) pick
up the handset or press “SPEAKER” to access the line and dial. Once it is connected,
please use the handset for conversation. (2) When the system is locked, (LCD shows
“LOCKED”) you must press “LOCK” and enter the correct system password in order to
unlock. Then, you can follow the steps stated in (1).
Answer an incoming call: (1) When the system is not locked or when the system is
locked but auto unlock incoming call (program option #4) is <ON>, you can pick up the
handset to answer a call. (2) When the system is locked but auto unlock incoming call is
<OFF>, you must enter the correct password and press “OK” to pick up the call.
Hang up : Return the handset to the phone cradle and the call will be disconnected. The
system will return to the previous status and settings.

OPERATION NOTE: THE “HANDS-FREE” OR “SPEAKER” FUNCTION IS NOT
ENABLED IN THIS VERSION OF SAFETALK FOR CLEAR OR SECURE
COMMUNICATIONS. THE HANDSET MUST BE USED FOR ALL
COMMUNICATIONS.
SECURE talk:
(1) After the call is connected, if you do not press “SECURE”, the conversation is
not under protection (clear mode). LCD shows “IN USE（CLEAR）”, and
“SECURE” LED is dark.
(2) After the call is connected, press “ SECURE’ to enter into secure link.
Note: If auto secure is <ON> (program option #7), the system will generate keys
automatically to establish the link. If auto secure is <OFF>, please enter
random numbers within 8 digits to initiate the secure link.
(3) During the secure link, LCD will show “CONNECTING” and some random
0,1, numbers. The SECURE LED will flash and you can hear connection noises
from the MODEM.
(4) When the secure link is established successfully, LCD will show “SECURED”.
The SECURE LED will be illuminated and 2 beeps can be heard to confirm the
secure mode is entered.
(5) If the secure link is not established, LCD will go back to “IN USE (CLEAR)”.
The “SECURE” will turn dark and 5 error beeps can be heard. The conversation
returns back to clear mode (not secure mode). Please make sure both parties use
the same model and that the GROUP ID setting (program option #3) is the same.
Then repeat steps (1) to (4) to try again.
(6) Upon entering secure mode, in order to ensure the security, the unit can not
return back to clear mode. You must hang up and place another call if clear mode
conversion is preferred.
During SECURE mode, the keypad is disabled. When pressing the dial pad buttons,

DTMF tones can still be heard. However, there is no corresponding function.
VII. Speed Dial

3. Dial: Review the SPD data and make sure it is correct. Press “SPEAKER” or
lift up the handset; the unit will seize the line and dial out automatically.
4. Delete：Press any SPD key, and press “DELETE” to erase the stored data.
VIII. Call Log
The unit can store 20 sets of outgoing number automatically.
1. Press “CALL LOG/DIAL” and use “▲VOLUME▼” to search for the number you
wish to dial.
2. After confirming, you can press “SPEAKER” or lift up the handset; the unit will seize
the line and dial out automatically.

4. If you want to delete all the data stored, press “CALL LOG/DIAL” ( but do not use
“▲VOLUME▼” to search) and the unit will display the total number of stored data.
Press “DELETE” and confirm “YES”; all the stored numbers will be deleted.
IX. Troubleshooting Tips
1. If the unit does not function properly as a basic telephone, please ensure the handset,
linecord, and adapter are well-connected.
Page: 11/
12
Page 12
2. If the unit does not light up or no display, check the AC outlet where the power adapter
is plugged in.
3. If the unit still is not working properly, plug another standard telephone in the wall
jack and confirm proper outside line connection.
4. When the unit can not establish secure link, please check:
(1) if both parties are using the same secure phone model. Secure links can
not be established between different models. Under these circumstances, the unit
will only function as a normal telephone.
(2) if both parties press the “SECURE” key. Only one party should initiate
the secure link.
(3) if the group IDs (program option #3) are different. The secure link can be
established only when both parties have set the same group ID.
(4) if you disable the auto secure function (program option #7). you must enter
a random number (less then 8 digits) and press “OK” to generate the encryption key
manually.
(5) If all of the above conditions are excluded, please note that the line condition,
especially the noise level, will affect the secure mode operation. Sometimes
redialing or trying the call later may allow proper operation. However, if the secure
linking is always difficult, there is a possibility that some recording devices or
extension line eavesdroppers exist and, thus, will inhibit SECURE operation.
5. If incoming calls can not be answered, please check if the system is locked and
auto-unlock incoming call (program option #4) is not enabled. If so, please enter the
correct system password and press “OK” to pick up the calls.
6. If you forget the password, the unit needs to be returned to the factory in order to
re-format. All the stored data and settings will be eliminated and altered to default
values since the factory is unable to retrieve the original password. This
re-formatting may incur a service charge.
