the box for my La Crosse atomic alarm clock state the Model no. be wt-6165u-spb , but the clock itself state that the Model no. be wt-2165led . I have no idea what `` u-spb '' be suppose to mean . Amazon have several La Crosse travel clock list on its web site which appear similar to this clock and each have a different model number , but all appear to have similar feature . like many electronic device on the market today , this clock be make in China . the label inside the door of the battery compartment state that it take a `` aa '' battery , but it actually take a AAA battery . the battery be not include in the box . after install a battery , the clock automatically pick up the correct time from the atomic clock after sit out overnight . however , the clock must be set manually for the correct time zone - it do not have a gp in it , so it have to be tell where it be by select the correct time zone . set everything else on this clock must also be do manually and be not very intuitive . fortunately , direction be print on the bottom of the base , as well as in a instruction manual include in the box . unfortunately , set the number on the display can be tricky , because the number move in only one direction - up . if you miss the number you want , you then have to move through the entire cycle and hope you can hit the correct number the next time around . it would have be helpful if there be a reverse button , but there be not . there be a led light on the inside right side of the display which make the time and other item display readable in the dark . the display can be illuminate by gently push the top of the clock back on the base . the same motion also activate the snooze feature . the display be also illuminate when the alarm go off , so you immediately know the time even if the room be dark . the snooze length be adjustable from 0 -lrb- for no snooze at all -rrb- to 59 minute . the clock also have two alarm and each have a distinctive ring . these be all convenient feature . the alarm can be deactivate by push any of the four button on the back , but do so reset the alarm for the same time the next day . to completely deactivate the alarm , the button for the actual alarm have to be push . I find that it be very easy to accidentally activate the alarm because only a brief push on the alarm button activate it . also , when the base be flip to the `` closed '' position , it cover only the display on the front of the clock - the button on the back be expose and the alarm can be accidentally activate if pressure be place on either of the two alarm button . therefore , when travel , I check the clock after unpack to make sure the alarm be not accidentally turn on by pressure from other item in my luggage . it would have be helpful if there be a way to deactivate the alarm button when travel , but this be another feature that be lack on this clock . this be a decent alarm clock , but there be room for considerable improvement .
