How do i increase the volume on the handset? Model KX-TG6021

The KX-TGA401C handset works with the KX-TG401x, KX-TG403X and KX-TG651x phone systems among others. If you have the appropriate base, see the suggestions below.

Does your handset read Ringer Off? Try setting the ringer volume. With the phone system in standby (no calls in or out for any handset), press Menu. Navigate using the Up/Down arrows to Initial Settings. Press Menu/OK. Navigate to Ringer Settings and press OK. Press OK again to enter the Ringer Volume sub-menu. Use the Up/Down arrows to set the ringer volume and press OK to save. Press Off to exit the menu system.

The other possibility is that the handset is not registered to the base. Note: only 6 handsets can be registered to the base. If you previously registered 6 handsets, you need to deregister some of them.
To register the handset, hold the handset near the base since you will need to press buttons on both. Press Menu on the handset and navigate to and enter Initial Settings. Navigate to Registration and press OK. Navigate to HS Registration and press OK. On the base, press and hold the Locator button for 5 seconds and the registration tone sounds. Press OK on the handset you are trying to register. If all the registered handsets start ringing, you triggered the Locate handset function. Press the Locator button again. Then do the press and hold step again. Only press OK on the handset when you hear the registration tone.

You can find the manual for the KX-TG4011 here: https://shop.panasonic.com/support-only/KX-TG4011N.html . The direct link to the manual is https://ftp.panasonic.com/telephone/om/kx-tg4011_mul_om.pdf . See page 21 for the directions to set the ringer volume.

I hope this helps.

(You can't register a handset to an incompatible base. The communication protocols don't work.)

The handset display is bad. This part can not be replaced because it is molded to the chassis of the phone. Replace the complete chassis or the handset and that would solve your problem.

To increase the volume, press cursor-up while on a call. If you go too far, press cursor-down to decrease the volume.

Adjusting the handset ringer volume. Press {^} or {V} repeatedly to select the desired volume while the handset is ringing for an incoming call. Here is the link to the above instruction.

Press the volume up. If you're on speakerphone it adjust the volume of the speaker. If you are on your handset it adjusts that volume.

when it asks for unlock press 0000. it will get unlocked... othere wise without lifting the handset press *#1234

The handset may have unregistered from the phone. The instructions to reregister it are in the manual, but I'll list them here for you.

1. On the handset, press MENU 001
2. On the base unit
For models KX-TG6021/KX-TG6022/KX-TG6023
Press and hold LOCATOR until the IN USE indicator flashes.
For models KX-TG6051/KX-TG6052/KX-TG6053/KX-TG6054
Press and hold LOCATOR/INTERCOM until the IN USE indicator
flashes.
After the IN USE indicator starts flashing, the rest of the procedure
must be completed within 1minute.
3. Press OK on the handset, then wait until a beep sounds.
4. Press OFF on the handset.

When you are talking on the phone press the up arrow on the circular big button until the volume increases to a level that you're comfortable with..

It first sounds as if the handset isn't charged properly. Check the battery status first. The manufacture advises to charge the system for approx. 7 hours before any use occurs. Second, make sure that the registration took, when programming the phone originally. I would de-register the handset by: 1 {MENU} i {0}{0}{2} 2 {3}{3}{5} i {OK} 3 Select the handset you want to cancel by pressing the desired handset number ({1} ? {4}). Then re-register by: 1 Handset: {MENU} i {0}{0}{1} 2 Base unit: KX-TG6021/KX-TG6022/ KX-TG6023 Press and hold {LOCATOR} until the IN USE indicator flashes. KX-TG6051/KX-TG6052/ KX-TG6053/KX-TG6054 Press and hold {LOCATOR/ INTERCOM} until the IN USE indicator flashes. LAfter the IN USE indicator starts flashing, the rest of the procedure must be completed within 1 minute. 3 Handset: Press {OK}, then wait until a beep sounds. 4 {OFF} Third, make sure that the display on the handset does not show "SP-Phone" in the display, if it does press the phone icon button. Fourth, Do you currently have voicemail from your phone service provider? If so, the answering machine will not answer. Make sure that the answering machine portion is turned on. Do this by: Press {ANSWER ON} to turn on/off the answering system. When the answering system is turned on, the ANSWER ON indicator lights. When the answering system is turned off, the ANSWER ON indicator turns off. If there are any further questions or comments, please post here. Please rate this solution through fix-it. Thank you

Try changing the speaker in the handset. I did and it solved my low volume problem.
