MEMORY STORAGE
BOOST FUNCTION - AMPLIFY INCOMING 
SOUNDS
1.  Press and hold the desired memory location (M1-M11 and 
Emergency) to store the number to.  The phone will beep to 
confirm you are in memory programming mode. See Figure 10.
2.  Enter the telephone number you wish to store (up to 31 
digits). If no button is pressed within 30 seconds, the phone will 
time out and goes back to idle or talk mode.
3.  Press the Hold/Program button to save the desired number.  
The phone will beep to confirm the number has been saved. See 
Figure 11.
4.  To change a Memory location, reprogram using the same 
procedure with the button to be changed.   
  1.  While on a call, press the BOOST button to engage the 
amplifier.  The XL40D has a BOOST button that controls the 
loudness of the receiver. See Figure 6. Once the BOOST button 
is pressed, an extra level of amplification is added over the entire 
range of the Volume Control. During a call, the BOOST button 
can toggle the Clarity Power function on or off according to the 
user’s needs. The BOOST button will reset automatically every time 
the phone is hung up for at least 5 seconds. The BOOST light will 
illuminate (blue) while the BOOST function is activated. 
Warning:  Volume may be at a high level. To protect 
hearing, lower the Clarity Power Volume Control before 
using the phone. 
  2.  Adjust the VOLUME slider to achieve the desired sound level 
(up to 50dB of amplification). The Clarity Power Volume Control 
adjusts the level of volume the handset both in Boost or non-Boost 
modes. The volume dial provides up to 16dB of volume before the 
BOOST button is activated. Once the BOOST button is pressed, 
the XL40D will provide up to 50dB of gain. See Figure 7. 
  3.  Adjusting the TONE switch allows you to customize your 
hearing experience. Since we all have different hearing preferences 
we suggest exploring each setting to find the one most comfortable 
for you. These four settings, along with our volume amplification, are 
part of the Digital Clarity Power (DCP™) technology. See Figure 8.  
The available settings are:
        1- Low Frequency emphasis: best used to hear low pitched 
sounds;
        2 - Flat frequency response: best for hearing aid users;
        3 - Clarity Power/High frequency emphasis response: best 
used to hear high frequency sounds;
        4 - Multi Band Compression with high frequency emphasis 
response: best setting for speech intelligibility.

Boost Override 
On the bottom of the XL40D, there is a Boost Override switch. 
When this is set to “ON” the Boost function is automatically enabled 
every time the phone is picked up. In standard use, when the Boost 
Override switch is set to “OFF” the Boost function will turn off after 
the phone is hung up. Setting this switch to “ON” is suggested if all 
the users of the phone need the amplification. Setting this switch 
to “OFF” is useful when people with varying hearing ability use the 
phone. See Figure 9.

Figure 5
If there is a power outage, the XL40D will maintain its full amplification 
for up to 48 hours with four AA alkaline backup batteries (not included).
The phone operates as a regular phone if there is no power or backup 
batteries. In this case, the indicator lights, the loud ringer, the lighted 
keypad and the amplification will be disabled; you will still be able to 
make and receive phone calls, but the extra amplification will not be 
enganged. We recommend installing batteries if you live in an area with 
frequent power outages.

OUTGOING SPEECH AMPLIFICATION (OSA)
This function amplifies your speech so it becomes louder to the 
person on the other end of the call. To enable this function, press 
and hold the BOOST/OSA button for 3 seconds (see figure 12). The 
phone beeps; the function can be enabled/disabled while on a phone 
call or in standby mode.   
To verify the function is active, lift the handset and check the light at 
the top of the phone. If the light is ORANGE, the function is active. To 
adjust the level of amplification for your voice, use the switch on the 
side of the phone labeled Outgoing Speech Amplification (OSA). You 
can choose between three levels: Low, Med and High (see Figure 13). 
To return to the default setting for your voice volume level, press and 
hold the BOOST/OSA button again for 3 seconds. You will hear a 
beep confirming that the function is disabled. To verify, the light at the 
top of the phone should not be orange when you are on a phone call.
NOTE: In order to experience the best audio quality for both parties 
during a call, we recommend you turn on this function only if your 
voice is too quiet. OSA is not active in speakerphone mode.
